When previewing a room, we normally do not have a Room object. Currently, when the RoomPreviewBar is instantiated without a room, it doesn't raise the PreviewRoomNotLoggedIn and JoinFromRoomPreview module lifecycle events, meaning that modules are unable to intercept previews of non-peekable rooms.
To fix this, make sure that we pass the room ID into RoomPreviewBar irrespective of whether we have a Room object, and use it to raise the module lifecycle events.
