Fix tasks (#5199)

## Query depth deprecation

I'm deprecating depth parameter in our graphql query / cache tooling.

## Refactor combinedFindManyRecordHook

The hook can now take an array of operationSignatures

## Fix tasks issues

Fix optimistic rendering issue. Note that we still haven't handle
optimisticEffect on creation properly
