mod_http_oauth2: Correct field name for HTTP response status code 'code' is used in the incoming side of the Prosody HTTP stack while 'status_code' is used on the response side. Not confusing at all. The default is 200 so this mistake had no real effect.

This module discards typing notifications sent to a bare host JID,
preventing error replies to be sent. These errors are harmless but can
be annoying sometimes if your client shows them prominently.
