[Milan Crha <mcrha src gnome org>]

commit 18a893fa83ebd10cea75831e9d9a7398a60c14ce

    gs-plugin-loader: Ensure correct list is used on the job when refining wildcards
    
    The plugin job is reused when refining the apps, including the wildcards,
    but the gs_plugin_loader_run_refine_internal() can be called multiple times,
    with different lists. Adding refined wildcards to the original list causes
    invalid data being provided to the called.
    
    Closes https://gitlab.gnome.org/GNOME/gnome-software/-/issues/1485
