amount_selected should never be decremented if already 0

Browse source 
this is probably more a workaround than a proper fix to a problem which
I think only happens if started with no dive loaded and then create one.
in that case, deselect_dive is called after saving the dive but probalby
before it was added to the dive list properly resulting in an underflow
of amount_selected.
