QTreeView: Fix expanding of spanning items

Browse Source 
When using HeaderView::ResizeToContents and
QTreeWidgetItem::setFirstColumnSpanned(), it happens that the position
of the branch icon is no longer in the first column and thus trying to
expand the item results in a selection change. Check for spanning when
determining the position.
