QTreeView - improve ItemNeverHasChildren slightly
QTreeViewPrivate has a private function hasVisibleChildren that
returns if an index has visual children. This can (and should)
check the ItemNeverHasChildren flag.
That will likely be an performance improvement and it will ensure
consistent behavior in error-situations. (The flag will then always
overrule even if the model is inconsistent)
