    window: Don't make windows on non-primaries sticky on restart
    
    When workspaces-only-on-primary is set, a window can be on all
    workspaces either because it is on a non-primary workspace, or
    because it was explicitly made sticky. Only the latter is reflected
    in _NET_WM_STATE, but both will result in a "magic" _NET_WM_DESKTOP,
    which we (and probably other WMs) use to set the initial sticky state.
    So to avoid confusing other WMs (or ourselves), make sure to only
    have _NET_WM_STATE_STICKY reflected in _NET_WM_DESKTOP when unmanaging.
