    screen: On monitors-changed, update the window monitor before resizing
    
    Since commit 14b0a83f64134fd6669d580558e10b4a225cb1d6 we store the
    main window monitor instead of computing it every time. This means
    that we must now ensure that it's updated before trying to use it
    which we do from meta_screen_resize_func() or else we'll crash on an
    assertion later on when removing a monitor:
    
    assertion failed: (which_monitor < workspace->screen->n_monitor_infos)
