Right now centrifuge does not send unsubscribe frames if unsubscribe happens between client and server connect frames, but there might be subscribe frames in the same batch with connect frame.
This leads to situation when server have channel in it's registry, but client think that there's no such subscription for channel. If client will try to subscribe to this channel again, it will receive already subscribed error from server.
