* Is this a change to an existing pending pledge requiring payment schedule changes.
*
* If the pledge is pending the code (slightly lazily) deletes & recreates pledge payments.
*
* If the payment dates or amounts have been manually edited then this can cause data loss. We can mitigate this to
* some extent by making sure we have a change that could potentially affect the schedule (rather than just a
* custom data change or similar).
*
* This calculation needs to be performed before update takes place as previous & new pledges are compared.
