QAbstractItemView: don't toggle selection on mouse move on some index 

In single selection mode, the current selection toggled when the user
pressed the left mouse + Ctrl key and then moved the mouse over the
item. This was introduced with 28a21d98ef
which added the possibility to deselect an item in single selection
mode.
Fix it by adding a check if the event was a mouse move event and use the
old codepath for it.
