Avoid useless handleTouchEvent call

The call when allReleased is true is a historical artifact: Originally
the call was necessary to generate a TouchEnd. Later the determination
of the event type got moved to QWindowSystemInterface. As a result the
call is completely superfluous since it will bail out immediately.
