* Fix handling SNS notifications for AWS SES
This fixes detection of email bounce by:
- removing hard requirement for email ID, ID in webhook msg never equals this in email_log
- gets bounce_score from user stats instead of nonexistent field in webhook msg
* Remove empty line
* Prettify access to EmailLog for parsing SNS notification
