    flatpak: Avoid plugin cache for temp installation
    
    Without this patch we get the unfortunate behavior that the GsApp object
    returned by gs_flatpak_create_app() in gs_flatpak_file_to_app_ref() does
    not have its metadata set correctly despite the info being available in
    the FlatpakRef object passed in to gs_flatpak_create_app() (e.g. the
    flatpak ref name and arch are unset). See
    https://gitlab.gnome.org/GNOME/gnome-software/-/merge_requests/1087#note_1305237
    
    (Milan came up with this patch)
