QGraphicsWidget was not working properly when ItemSendsPositionChanges is false

The geometry was not properly set because QGraphicsWidget rely on itemChange
to update its own geometry. Now when calling setPos we also ensure that
for a widget the geometry will be up to date. Setting the flag
ItemSendsPositionChanges to false for a given widget will give a small
performance boost.
