Helper to fix prefetching fetch spec to abstract entities. when batch fetching across flattened relationships and targeting abstract entities, we end up with GIDs that contain the abstract, not the concrete. So the objects can't be instantiated. If we add the schema based qualifier to the relationship beforehand, everything works as expected.

Parameters:

dbc - database context

fetchSpec - original fetch specification

relationshipName - relationship name to abstract entity

sourceObjects - unused

context - unused

Returns:

adjusted fetch specification
