    flatpak: Invalidate caches when app data rescan fails
    
    Otherwise the gnome-software caches may not reflect actual state of
    the flatpak data, pretending everything is up-to-date even it's not.
    
    This could happen for example when enabling a flatpak remote
    in the Repositories dialog and closing the dialog early, which
    cancels the operation, maybe in the middle of downloading appstream
    data from the server.
