ShortcutWidget: override shortcuts in the way they are meant to be (#10075)

Browse Source 
I would say "by the books" but the documentation was not really clear.

Problems with the logic of the previous implementation were exposed in Qt 5.6 by
commit <https://codereview.qt-project.org/125142>.

<http://mid.gmane.org/20160510070413.wzjpk4w4turnx6pr@cotopaxi>

Note that ShortcutOverride events are used elsewhere in the code where they may
need to be corrected in the same way.
