Title:  HG-321: Renamed host to wiki; Added refferer to logging

Seems like `host` is stripped somewhere down the stream to Kibana, that's why it is renamed to `wiki` here.
Added `referrer` which should help tracking down errors on production.
Moved the fields a little to make the dev debug easier to eye-scan.
