    auto-move-windows: Exclude sticky windows from empty-check
    
    We modify gnome-shell's workspace tracker to only remove empty
    workspaces from the end. However we currently don't take into
    account that sticky windows appear on all workspaces, so those
    are preventing any workspace from getting removed at the moment.
    
    Exclude them when determining whether a workspace is empty to
    get the expected behavior.
