Title: Fixes 4231: untimely termination of entity creation if can't write to owner as container

Prevents termination only if both are true: can't write to container and can't write to owner
Moves group container permissions check to groups plugin

I would also look into inconsistencies in owner_guid vs page_owner_guid (the latter is not always a user or a group)
