SetRoomState/SetRoomMembership 'revision' event consistency

[Gnuxie]

So I was wondering if I needed to create a new listener specifically for when the ProtectedRoomsManagergets a call to addRoom. Instead of just abusing the existing 'revision' event in the setRoomState and membership objects.

When a new policy list is added to the PolicyListsConfig, the issuer manager creates a revision that incorporates all these new changes. But that's because the revision represents the final result of all config and fancy filtering.

So the thing is the protection handles for handleStateChange and handleMembershipChange are called when the setRoomState emits the revision event.
