Improve notifier logs

[xuset]

The logs currently contain very little information and are not helpful.

What they currently look like:

  2 listening on *:8060'ENOTFOUND', syscall: 'getaddrinfo' }
  3 registering transaction { transaction_uuid: '12433778334281581315-1455381840745331' }
  4 registering transaction { transaction_uuid: '10535386475720166119-1455402069219675' }
  5 Notifying listeners of change to transaction 12433778334281581315-1455381840745331
  6 registering transaction { transaction_uuid: '12433778334281581315-1455381840745331' }
  7 registering transaction { transaction_uuid: '10535386475720166119-1455402069219675' }

The updated logs should at least contain the timestamp and the ip that initiated the request
