Refactored query result getter handlers to support recursivity (#8497)

The `QueryResultGettersFactory` that is called on every query return to
was called only on the first level of relations because recursivity
wasn't implemented.

In this PR I implement recursivity and add some typing for the possible
forms a GraphQL query field can take.

This PR will fix any issue we have with pictures that were losing their
token (here for person.avatarUrl)
