    runDialog: Don’t add empty input to history
    
    If the input is empty, there’s no point in adding it to the history –
    it’ll just be mildly annoying when the user has to skip past it next
    time they consult the history.
    
    Fixes https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3183.
