perf: replace TypeOrm `findOne` queries including relations with `find`

[S3bb1]

What issue is this PR fixing

This PR addresses a performance issue with TypeORM (https://github.com/typeorm/typeorm/issues/5694)

When using findOne() with attached relations, TypeORM executes two queries:

query: SELECT DISTINCT "distinctAlias"."Identifier_did" AS "ids_Identifier_did" FROM (SELECT "Identifier"."did" AS "Identifier_did", "Identifier"."provider" AS "Identifier_provider", "Identifier"."alias" AS "Identifier_alias", "Identifier"."controllerKeyId" AS "Identifier_controllerKeyId", "Identifier__Identifier_keys"."kid" AS "Identifier__Identifier_keys_kid", "Identifier__Identifier_keys"."kms" AS "Identifier__Identifier_keys_kms", "Identifier__Identifier_keys"."type" AS "Identifier__Identifier_keys_type", "Identifier__Identifier_keys"."publicKeyHex" AS "Identifier__Identifier_keys_publicKeyHex", "Identifier__Identifier_keys"."meta" AS "Identifier__Identifier_keys_meta", "Identifier__Identifier_keys"."identifierDid" AS "Identifier__Identifier_keys_identifierDid", "Identifier__Identifier_services"."id" AS "Identifier__Identifier_services_id", "Identifier__Identifier_services"."type" AS "Identifier__Identifier_services_type", "Identifier__Identifier_services"."serviceEndpoint" AS "Identifier__Identifier_services_serviceEndpoint", "Identifier__Identifier_services"."description" AS "Identifier__Identifier_services_description", "Identifier__Identifier_services"."identifierDid" AS "Identifier__Identifier_services_identifierDid" FROM "identifier" "Identifier" LEFT JOIN "key" "Identifier__Identifier_keys" ON "Identifier__Identifier_keys"."identifierDid"="Identifier"."did"  LEFT JOIN "service" "Identifier__Identifier_services" ON "Identifier__Identifier_services"."identifierDid"="Identifier"."did" WHERE (("Identifier"."did" = $1))) "distinctAlias" ORDER BY "Identifier_did" ASC LIMIT 1 -- PARAMETERS: ["did:ethr:xyz"]
query: SELECT "Identifier"."did" AS "Identifier_did", "Identifier"."provider" AS "Identifier_provider", "Identifier"."alias" AS "Identifier_alias", "Identifier"."controllerKeyId" AS "Identifier_controllerKeyId", "Identifier__Identifier_keys"."kid" AS "Identifier__Identifier_keys_kid", "Identifier__Identifier_keys"."kms" AS "Identifier__Identifier_keys_kms", "Identifier__Identifier_keys"."type" AS "Identifier__Identifier_keys_type", "Identifier__Identifier_keys"."publicKeyHex" AS "Identifier__Identifier_keys_publicKeyHex", "Identifier__Identifier_keys"."meta" AS "Identifier__Identifier_keys_meta", "Identifier__Identifier_keys"."identifierDid" AS "Identifier__Identifier_keys_identifierDid", "Identifier__Identifier_services"."id" AS "Identifier__Identifier_services_id", "Identifier__Identifier_services"."type" AS "Identifier__Identifier_services_type", "Identifier__Identifier_services"."serviceEndpoint" AS "Identifier__Identifier_services_serviceEndpoint", "Identifier__Identifier_services"."description" AS "Identifier__Identifier_services_description", "Identifier__Identifier_services"."identifierDid" AS "Identifier__Identifier_services_identifierDid" FROM "identifier" "Identifier" LEFT JOIN "key" "Identifier__Identifier_keys" ON "Identifier__Identifier_keys"."identifierDid"="Identifier"."did"  LEFT JOIN "service" "Identifier__Identifier_services" ON "Identifier__Identifier_services"."identifierDid"="Identifier"."did" WHERE ( (("Identifier"."did" = $1)) ) AND ( "Identifier"."did" IN ($2) ) -- PARAMETERS: ["did:ethr:xyz","did:ethr:xyz"]

the two queries are specially gaining performance when doing pagination (where we have skip and take). In the datastore we explicitly don't want/need to page, just getting the first entry back.

When executing the query with just a "find" and taking the first element in the array, TypeORM executes only one query:

query: SELECT "Identifier"."did" AS "Identifier_did", "Identifier"."provider" AS "Identifier_provider", "Identifier"."alias" AS "Identifier_alias", "Identifier"."controllerKeyId" AS "Identifier_controllerKeyId", "Identifier__Identifier_keys"."kid" AS "Identifier__Identifier_keys_kid", "Identifier__Identifier_keys"."kms" AS "Identifier__Identifier_keys_kms", "Identifier__Identifier_keys"."type" AS "Identifier__Identifier_keys_type", "Identifier__Identifier_keys"."publicKeyHex" AS "Identifier__Identifier_keys_publicKeyHex", "Identifier__Identifier_keys"."meta" AS "Identifier__Identifier_keys_meta", "Identifier__Identifier_keys"."identifierDid" AS "Identifier__Identifier_keys_identifierDid", "Identifier__Identifier_services"."id" AS "Identifier__Identifier_services_id", "Identifier__Identifier_services"."type" AS "Identifier__Identifier_services_type", "Identifier__Identifier_services"."serviceEndpoint" AS "Identifier__Identifier_services_serviceEndpoint", "Identifier__Identifier_services"."description" AS "Identifier__Identifier_services_description", "Identifier__Identifier_services"."identifierDid" AS "Identifier__Identifier_services_identifierDid" FROM "identifier" "Identifier" LEFT JOIN "key" "Identifier__Identifier_keys" ON "Identifier__Identifier_keys"."identifierDid"="Identifier"."did"  LEFT JOIN "service" "Identifier__Identifier_services" ON "Identifier__Identifier_services"."identifierDid"="Identifier"."did" WHERE (("Identifier"."did" = $1)) -- PARAMETERS: ["did:ethr:xyz"]

This results in a performance boost when generating VPs (in our case the "find" executes in half of the time as with "findOne")

Hi @mirceanis

I checked all findOne references in the code. The only "bad" findOnes are those which have included relations setting.
