Fix TouchPoint::lastPos() after TouchPointStationary only events.

lastPos is copied from the last point's position, and the position has
to be resolved according the the receiving item's transformation.

However, if a QTouchEvent contains only stationary points, it won't be
delivered, it's pos()/rect() will still be uninitialized, and the
touch point of the next event will be delivered with the uninitialized
pos() as it's lastPos().

This patch makes sure that the lastPos() won't be filled with a
previous incomplete stationary point state even if the platform is
sending us stationary-point-only touch events.
