Working on current #develop branch (because I need other fixes included there), the __my_messages__ stream no longer includes the room meta object (the second argument emitted in the stream).

It's created here, on the access check when the room object is fetched.

I have a fix to get the room object in the original publish method instead. I will submit that now, but this is a pretty critical change and I'd like to understand it and know how it can happen.
