We need to deal with this, it's ok when updating a notification status from delivered to delivered. But the DailySortedLetter counts are being doubled. Adding the file_name to the table as a unique key to get around this issue. It will mean we have multiple rows for each billing_day, but that's ok we can aggregate that. This will also give us a way to see which file created which count.
