Fix crash after "Remove QT_WA and non-Unicode code paths, dropping Win9x and NT support"
tst_QGraphicsProxyWidget crashed because the QAlphaWidget tried to access a
deleted widget. Before we had the if check, but that was removed
with this commit: 55137901. Completely wrong, we must check the widget pointer
before using it.
