Bug 24380: Backdated returns do not update fines unless CalculateFinesOnReturn is enabled

In Koha 18.11 backdating a return triggered a recalculation of the fine. This was removed in bug 14591, and I believe it was in error. The bug report itself has no justification for the change in behavior.

Test Plan:
1) Disable CalculateFinesOnReturn
2) Backdate an overdue with fines, note the fine does not change
3) Apply this patch
4) Repeat step 2
5) The fine should be updated!
