Error when checking is_auth_alive #71
Description
When using oauth_client.is_auth_alive the response from the server (when auth is expired) is HTML (shown at bottom), so when trying to json.load this in the json_response decorator an unhandled exception occurs: raise ValueError("No JSON object could be decoded")
<title>401 Unauthorized</title>Unauthorized
The server could not verify that you are authorized to access the URL requested. You either supplied the wrong credentials (e.g. a bad password), or your browser doesn't understand how to supply the credentials required.
