[BUG] _explain=analyze only returns plan for first SQL query

[MFAshby]

Describe the bug

_explain=analyze only explains the first SQL query and not any subsequent ones that are part of the same FHIR request.

Severity

Minor

Steps to reproduce the behavior:

• Have a FHIR store with Patient and Consent resources
• Make API call

  GET /fhir/Patient?identifier=https://fhir.nhs.uk/Id/nhs-number%7C9990577382&_revinclude=Consent:patient&_explain=analyze

Expected behavior

A result showing query and plan for every SQL query made in the request.

Screenshots

Actual query plan is only showing 1 query and missing second query over consent resource

query:
  - >-
    SELECT "patient".* FROM "patient" WHERE "patient".resource @> ? LIMIT ?
    OFFSET ? 
  - >-
    {"identifier":[{"system":"https://fhir.nhs.uk/Id/nhs-number","value":"9990577382"}]}
