tx logging: only update logged tx id if all loggers logged

Prevents the case where the logged id is incremented if a newer
transaction is complete and an older one is still outstanding.

For example, dns request0, unsolicited dns response, dns response0

would result in the valid response0 never being logged.

Similarily this could happen for:
  request0, request1, response1, response0

which would end up having request0, request1 and response1 logged,
but response0 would not be logged.
