This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
* 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
