Pea Tyczynska b81c7dd5ee Put status codes in logs to see if lack of detailed status is
us not recognising a code or provider not having sent the detailed
status.

It seems like Firetext is sometimes sending us permanent-failure
without detailed status. It could be due to:
- them really not sending any detailed status
- them sending a status code we don't recognise
- them sending 000 code that means 'no errors', which we ignore

To see which one it is, and to debug such issues quicker in the
future, this PR adds status and detailed status codes to the logs.
