    font-view: match the font face when getting an iter to update the button
    
    Instead of matching the file name, match the font face (i.e. its
    family/style names).
    Since we refresh the button appearance when installing a font over to
    ~/.fonts, the file path will not match at that point, since the preview
    will still be showing the old uninstalled file.
