    Fixed gtk_cell_area_stop_editing() to property notify when editing is not canceled
    
    This fixes bug 653289, in gtk+-2 gtk_tree_view_stop_editing() was previously
    responsible for notifying with gtk_cell_editable_editing_done(), this detail
    was missed when porting the cell renderer management to GtkCellArea.
