Relookup Entity Save ID if was null during precache
Should fix #1280

Citizens hijacks entity map, and im guessing under the right conditions
the result might actually be null during entity creation

Pre the cache patch, the id is looked up on save, so it was fine.

Now, if its null and the save ID is requested, we will try to look
it up again and cache it if found.
