    files-view: Remove new empty folder name suggestion
    
    When we choose to create a new empty folder, while selecting one or more
    folders, Nautilus offers as suggestion the common filename prefix. In the case
    of one selected folder, the suggestion is the name of the folder.
    
    In this patch, we changed this so the common filename is displayed only in the
    "with selection" case.
    
    Fixes https://gitlab.gnome.org/GNOME/nautilus/issues/206
