Fix relations in search queries (#8595)

We were not handling relations in the search resolver, which started
being an issue as we query those relations in the combinedSearch queries
(introduced here https://github.com/twentyhq/twenty/pull/8564); they
were nullified in the response payload. The response was overwriting
findManyRecords results in the cache as it contained the exact same
fields.

So we now
1. Handle relations in the search resolver
2. Stop querying relations in search queries (no use)
