    Fix installing web applications
    
    We only want the PackageKit plugin to match up installed desktop files with
    package names. If we do this for all components we end up searching for the
    thing that installed /usr/share/app-info/xmls/fedora.xml which is appstream-data,
    which we really don't want to remove.
    
    Luckily, the PackageKit plugin gets confused and just returns an unhelpful
    error in this case.
    
    Fix the problem by only adding the extra metadata for desktop, AppData or
    MetaInfo files.
