    MacOS: fix content type check vs. mime check to show folder icons
    
    In MacOS the file selection dialog does not show folder icons.
    With this fix the folder icons are shown. The bug is described
    in:
    
    https://bugzilla.gnome.org/show_bug.cgi?id=788936
    
    This bug fix is only partial, because this fix is only the
    last resort when no mime information is available.
