    apps-menu: Catch menu tree entries we can't resolve to an app
    
    The default .menu file still contains a number of legacy directories that
    have been deprecated for over 15 years, which GIO (and in extension the
    shell's AppSystem) ignore. Encountering such an entry currently triggers
    an exception and an entire category ends up empty, fix this by silently
    skipping over the offending entry.
