QGraphicsProxyWidget: Don't crash within setWidget() when a child proxy has no assigned widget
QGraphicsProxyWidget::setWidget() is checking if the newly assigned
widget is already assigned to a child proxy widget without checking if
the child has a widget assigned at all which lead to a nullptr reference
if it is not the case.
Therefore check if the assigned widget is a valid pointer.
Fixes: QTBUG-15442
