Error management when tokken is not correctly configured

When the tokken as expired errors are not managed. For instance trying to search for a user would return the error Too many users found for email XXX, aborting. because the request for users returned {'error': 'invalid_token', 'error_description': 'Token is expired. You can either do re-authorization or token refresh.'} (i.e. an dictionnary with more than 1 element...)
