QGuiAppPriv: don't clear target and window for TouchCancel 

It's nice not to leave garbage in QPointingDevicePrivate::activePoints
between events; on the other hand, this garbage doesn't matter, because
every press event sets the target and window independently, without
caring what was stored there from before.  But it was wrong to clear
it before we've even delivered the TouchCancel event.
