QGraphicsItem::setOpacity(0.0) does not trigger an update.

The problem was that we discarded update requests for fully
transparent items, which is correct, but we even did that
when the update was issued from QGraphicsItem::setOpacity.
We don't have to, and shouldn't, consider the opacity in
that case. Whenever we reach the fullUpdateHelper call in
setOpacity it means we have to do an update regardless of
the current opacity (oldOpacity was not 0.0 if the
currentOpacity is 0.0).

Auto-test included.
