Fix regression caused by r76974 (inserting first choice item to wxEnumProperty).

Browse Source 
This is a modified way of handling insertion of the first choice item to wxEnumProperty. Previous method based on special value (wxNOT_FOUND) used to indicate empty collection caused regression in wxPGProperty::DeleteChoice(). Currently, the size of the collection is checked directly in wxPGProperty::InsertChoice().
