qdoc: Sort qualified names correctly in generateCompactList()

qdoc was not sorting qualified class names correctly for inclusion in the
All Classes list. For example, QAttribute (Qt3DRender) was being placed in
the list in the position for Qt3DRender::QAttribute instead of the position
for QAttribute (Qt3DRender). This update corrects that bug.
