Mateusz Mandera 89d1f1f385 messages: Eliminate redundant realm fetch in has_message_access. ...

Accessing .realm will cause a fetch query from the database if the
attribute hasn't been fetched already earlier in the codepath. That's
completely redundant if we're just comparing realms, and we should only
access .realm_id attribute. This seems to eliminate a query in some
codepaths, which is nice in this performance-sensitive function.
