Merged PR 56612: Add missing setType call to OrderSaveAfter

## What's being changed

OrderSaveAfter.

## Why it's being changed

We fixed the incorrect queue topic name already, but in fact we also needed to `setType`, otherwise the SubscriptionData class will throw a type error on `getType`.

## How to review / test this change

- Subscribe an email address
- Check out as a guest with this same email address
- See the order complete
- Go into orders admin, cancel the order
- See the order cancelled
