Calling gtk_list_box_remove_all() is a no-op with a bound model; after the introduction of the remove_all() method in 49e56fc7, we were left with row widgets after the dispose() call chained up. We could restore the explicit unparenting inside dispose() instead of calling remove_all(), but since the bound list model is provided by the user of GtkListBox, it's more appropriate to unbind it in the dispose() implementation, to avoid any potential reference cycle (especially in higher level languages that have no explicit reference acquisition). We clean up the bound model, and its associated state, if any; and then we remove all the row widgets that are left.
