Capture event that triggers error

[mingard]

Currently when an event triggers an error, the event itself is not capture. Propose adding this to the logging

{"name":"dadi-web","hostname":"ip-172-31-12-39","pid":19405,"level":50,"module":"event","msg":"{ [TypeError: Cannot read property 'urls' of undefined] statusCode: 404 }","time":"2016-11-16T13:41:54.265Z","v":0}

As part of this ticket, it would be important that event errors do not crash the service but are always caught
