    files-view-model: Focus selection when setting it
    
    In all cases when we set selection, we also want to set focus.
    Otherwise, moving the focus is going to disrupt user workflow.
    
    Solution based on Corey Berla's review suggestion.
    
    Fixes https://gitlab.gnome.org/GNOME/nautilus/-/issues/2087
