Selection: automatically unselect old selection in selectDives()

Browse source 
DiveListView::selectDives() would only select new dives but not clear
the old selection. Thus, callers would have to clear the selection
first. That would lead to two selection-changed signals.

Move the unselectDives() call into DiveListView::selectDives().
The DiveListView has an internal flag to prevent double signals.
