The congress-server previously returned the status api response as:
{'results': [{'last_updated': 'now'}, {'last_error': 'foo'}]} though
it would be better if it returned it as:
{'last_updated': 'now', 'last_error': 'foo'}. This patch fixes the client
side of this api call and also corrects the cli command to say show over list.
There is also a server side patch as well that is required for this.
