Otherwise `moonfire-nvr check --delete-orphan-rows` can fail with this
error:
```
I0305 113848.655 main moonfire_db::check] Deleting 2 recording rows
E0305 113848.655 main moonfire_nvr] Exiting due to error: FOREIGN KEY constraint failed
```
The new order matches the online system's `db::raw::delete_recordings`.
