Bug 27927: Prevent renewal on lost forgive

The `RenewAccruingItemWhenPaid` preference should only renew upon
payment (and writeoff) and not upon automatic forgival triggered by
`WhenLostForgiveFine`.

Test plan
1/ Enable `WhenLostForgiveFine` and `RenewAccruingItemWhenPaid`
2/ Checkout an item and backdate it's due date
3/ Run longeroverdue.pl to mark the item as lost and create the fine
4/ Confirm that the item is not renewed as part of the process
5/ Signoff
