Comment 2 for bug 2028851

There is an error in the tempest test where the _get_console() method always try to get the console for the
self.server, which is created in setup, but test test_get_console_output_server_id_in_shutoff_status creates its own server and uses _get_console() method to check the console. So test creates its own server but try to get the console for a different server.
