In SHA 51914375b6 the rubberband
selection was fixed, so it followed the scene-point on mousemove.
However wheelEvent could move the view - but avoid update of the
rubberband (that would not be updated until next mouse-move).
This patch fixes that (and generally improves rubberband behavior)
since QGraphicsViewPrivate::mouseMoveEventHandler is called by
replayLastMouseEvent, which is called from various places,
where we need to update the rubberband (e.g scrollContentsBy).
