specs: Clarify rejection for touch events on current owner
The current owner never gets a TouchUpdate(PendingEnd), that event is
superfluous for the owner. The owner receives a TouchEnd when the touch
physically ends. If the touch is still active, the owner receives a
TouchEnd after rejecting the touch.
