    lists: Don't create a ghost selection
    
    If the model passed to gtk_...view_set_model is not
    a selection model, create a GtkNoSelection for internal
    purposes, not a GtkSingleSelection. The single selection
    is confusing because it maintains a selection state that
    cannot be accessed from the application side.
