    ui: Go out of selection mode after removing all boxes
    
    If you delete all your boxes, we currently stay in selection mode,
    and the user has to click on 'Cancel' to go out of it. After this
    commit, we go out of selection mode when the collection view gets
    empty after some changes in selection mode.
