Unlike an acceptable effect in QTableView + QTreeView
setAdjustPolicy(QAbstractScrollArea::AdjustToContents)
unfortunately didn't work for QListViews (and QListWidget).
This patch corrects QListViews AdjustToContents
behavior.
[ChangeLog][QtWidgets][QListView] A more correct implementation
of QListView::viewportSizeHint has been made. That
implies that setting the sizeAdjustPolicy to AdjustToContent
on QListView and QListWidget will now cause the view to
size after the contents and avoid scrollbars.
