Agent simple inverse queries

@Connoropolous @pospi there seems to be a gql level error when trying to query the commitmentsAsProvider/commitmentsAsReceiver fields of `agent, as done here: https://github.com/h-REA/hREA/blob/7f651d3424651fa16dbf38862a1276e0610b5699/test/agent/test_agent_links.js#L87 and here: https://github.com/h-REA/hREA/blob/7f651d3424651fa16dbf38862a1276e0610b5699/test/agent/test_agent_links.js#L96

The resolver functions aren't even executing: https://github.com/h-REA/hREA/blob/7f651d3424651fa16dbf38862a1276e0610b5699/modules/vf-graphql-holochain/resolvers/agent.ts#L57

which makes me suspect it has something to do with gql syntax and the fact that in the schema we define inputs: https://lab.allmende.io/valueflows/vf-schemas/vf-graphql/-/blob/sprout/lib/schemas/bridging/agent.commitment.gql#L53-54

Any ideas, do I need to define more input parameters to: https://github.com/h-REA/hREA/blob/7f651d3424651fa16dbf38862a1276e0610b5699/modules/vf-graphql-holochain/resolvers/agent.ts#L57

I confirmed that the indexing is working properly and calling query_commitments returns the relevant CommitmentConnection object. So this is defintely a gql related issue, maybe something to do with the fact that Agent is an interface then Person and Organization implement that interface?

EDIT: actually the error does seem to be coming from zome side, something to do with construct_response

Glad you figured it out!

A couple of issues with those parameters- I would parameterize commitmentsAsReceiver too.

The other issue is passing all of them- it's actually considered undefined behavior to send all of them. You can omit after and before since we are starting from the end, and should only pass last to get the latest, not before. See https://relay.dev/graphql/connections.htm#sec-Pagination-algorithm for more info.

@pospi there seems to be an error with get_link_fields: https://github.com/h-REA/hREA/blob/fc7d80565356e95e010610d5b866aa28e4166473/zomes/rea_agent/lib/src/lib.rs#L139-L165

It should be returning a vec of CommitmentAddresses, but it isn't. I'm assuming the error is either from read_index!() or create_index!() on the commitment side of things: https://github.com/h-REA/hREA/blob/fc7d80565356e95e010610d5b866aa28e4166473/zomes/rea_commitment/lib/src/lib.rs#L36

Although I'm a bit stumped as to why its not working.

To be more specific, I printed the output of the person query (in the api code), which should contain the commitmentsAsProvider and other related fields, but they are excluded from the object, which means these are empty vecs in get_link_fields

@Connoropolous @pospi this is ready for review and should close #298
