Change Details

I noticed this on the new EventLogging [error dashboard](https://logstash.wikimedia.org/#/dashboard/elasticsearch/eventlogging-errors). We are second-worst in schemas with errors. It is passing a string for eventId where integer is expected: ``` u'341802' is not of type u'integer' ``` ``` 3226394 EventLogging {"event":{"version":"1.5","eventId":"341802","notificationType":"welcome","notificationGroup":"positive","sender":"-1","recipientUserId":3810264,"recipientEditCount":0,"deliveryMethod":"web"},"schema":"Echo","revision":7731316,"clientValidated":false,"wiki":"mediawikiwiki","recvFrom":"mw1007","timestamp":1445450213,"webHost":"127.0.0.1:9005","userAgent":"curl/7.35.0"} ``` https://meta.wikimedia.org/wiki/Schema:Echo
