    surface-actor-wayland: Fix assumption in get_current_primary_view
    
    Unlike the multi-view path, the optimized/single-view one doesn't check
    if the surface-actor is really present on the view. That is the case
    whenever it's hidden - e.g. when the window is minimized.
    
    Fixes 3b7137cb359
