Don't forget not-persistent rooms in load_permanent_rooms

Only non-persistent rooms that we are storing are those that were hibernated
but also have mucsub subscribers in them. I don't think it makes sense to
destroy those rooms on restart/reload if we didn't destroy them in first
place when last member did leave room, let just handle those rooms like
they are persistent, and kill them only when all user unsubscribe from them
or they are destroyed from api.
