Xi: Fix TouchEnd to TouchUpdate change for one accepted grab

If there is only one listener of a touch, the listener is a grab, and is
accepted before the touch has ended, the current code will not end the
touch record when the touch does end.

This change adds a listener state for when a touch is accepted but has
not yet ended. We now keep the touch record alive in this state, but end
it when the touch ends.
