           Summary: fines calculation erroneous when a repeatable holiday is
                    added.

Adding a repeatable holiday creates holidays retroactively for Koha's calendar
module.  fines.pl balks when it sees an overdue fine calculation where amount
!= amountoutstanding (it assumes a payment was made, so tries to adjust the
amountoutstanding appropriately).  This fails if the calendar module reports a
smaller number of fine-inducing days on one run of fines.pl than it did on the
previous.

Symptoms:
Overdue charges appear on patron accounts with Amount Outstanding > Amount.

Steps to reproduce:
  * run fines.pl with some overdue items.
  * set calendaring sysprefs to ensure fines calculations take the calendar
into account
  * add a repeatable holiday that will fall within the overdue period of your
overdue items
  * run fines.pl again
  * the new Amount is the correct fine.  Amount Outstanding is now incorrect,
as it includes the fines on the days that are now holidays.

amountoutstanding > amount is nonsensical from Koha's standpoint, and should
not occur.
