fixed typo in room subscribtion

room/roomName
publishCreate and publishDestroy no longer omit client from instance room subscriptions

The requesting socket shouldn't be told about the instance it has just created, but it should be subscribed to the new room. Similarly, when an instance is destroyed, the requesting socket shouldn't be told about it, but it should be unsubscribed from future room updates.
