    appstream: Fix refining wildcard shell extensions
    
    The shell extensions plugin uses the "shell-extensions::uuid" custom
    metadata key for installation method. Check that when refining wildcard
    apps in the appstream plugin and allow matches if the custom key is set.
    
    This fixes opening shell extensions from the tweak tool that regressed
    with commit 9198056 that removed that global cache.
    
    Fixes: https://gitlab.gnome.org/GNOME/gnome-software/issues/430
