[libsecret] Validate that we have attributes when looking up

commit c85cadce76b99e5a3b20a9408edff09df3d7c777
Author: Stef Walter <stefw gnome org>
Date:   Tue Jul 10 21:37:20 2012 +0200

    Validate that we have attributes when looking up
    
     * When matching items, make sure we have attributes if
       no schema name was included in the match
     * This is particularly important because we don't want to
       remove all the items.
