    testsuite: Redo listbox sort test
    
    This test was relying on gtk_container_forall returning
    the visual (ie sorted) order of children, while iterating
    with the widget dom api gives the insertion order.
    
    Instead of using gtk_container_forall, use
    gtk_list_box_row_get_index to reconstruct the visual
    order.
