Ben Thorner ed379a3724 Fix out-of-date rows in ft_notification_status ...

This can happen in the following scenario (primarily for letters):

1. A service has a mixture of "delivered" and "sending" letters,
which the status task aggregates into two rows:

  sending | 123
  delivered | 456

2. After the 7 day retention has passed, only the "delivered" letters
will be archived [^1].

3. The status task now looks at the history table [^2], which means
it only sees the "delivered" letters.

4. The "sending" letters are eventually "delivered" and archived (before
the 10 day aggregation cutoff).

5. But the status aggregation task doesn't run.

This commit fixes (5).
