[pyramid] Retrieve user's groups using a custom RQL instead of user's groups property With cubicweb 3.24, user.groups is set lazily and so retrieving it at this point will cause a traceback because the connection is not yet entered. Also, user doesn't accept anymore groups and properties arguments.
