Do not enrich relations when id undefined (#13530)

Fixes https://github.com/twentyhq/twenty/issues/13428
We perform the call enrichment even with id undefined. It returns the
first item in DB.

Adding two more fixes related to filters:
- Conditions title
- Fixing placeholder color for select control (only other impacted field
is in Advanced filters)
