When you select the same sort order that's already selected, the currently-checked
sort order description (the human-readable ascending/descending items) gets unchecked
in slotSortTriggered() yet the ascending/descending items items only get checked in
slotSortOrderChanged(). Because the order hasn't gotten changed, neither one gets
checked again.
This patch fixes the problem by not unchecking them in the first place.
