Properly forward queued touch events

If a touch-event is added to an empty TouchEventQueue and should not be
forwarded to the renderer, it is ack'ed to the client immediately.  However,
this ack may trigger follow-up events synchronously, which would be queued but
never forwarded to the renderer.  Properly forward the follow-up events when the
first event reaches an empty queue but was never forwarded.
