Add aws-ses back in for the sync error emails.

These emails have more debugging information than errbit, we track the
last few sql queries and the data in the importer which helps when debugging issues

This is extra information in addition to errbit, not replacing it.
Fix spec failure due to not setting dates correctly

We are relying on the dates in the factory which are not relative the
dates in the spec, and they are now failing.

We need to review all specs with dates to ensure that factory objects
have dates set explicitly.

Add sed commands for database import

The production database dump contains various entries which try to set definer
of views to be an account which does not exist in the development VM. This will
cause errors when you try to import it in development:

```
ERROR 1227 (42000) at line 7199: Access denied; you need (at least one of) the SUPER privilege(s) for this operation
```

The offending lines look like:

```
/*!50001 CREATE ALGORITHM=UNDEFINED */
/*!50013 DEFINER=`tariff_temporal`@`%` SQL SECURITY DEFINER */
```

We can safely remove those in development.

Usage:

```
sed -f path/to/prod2dev.sed production-dump.sql > development-dump.sql
```
