Subject: [PATCH] Bug 27079: Floating point comparison correction

We cannot compare calculated values directly as those calculations may
have introduced floating point differences.  We have the
Koha::Number::Price->round function to consistently round the floating
point number to a decimal with 2 points precission for comparison.

Test plan
1/ Set a circ rule to have a .15 per day fine
2/ Issue an item of this type to a borrower (making it 12 days overdue
   by setting the due date to 12 days in the past)
3/ Run the fines job:
4/ Pay the fine for the patron
5/ Check in the item
6/ Note that the patron does not have an 'Overpayment refund' of $0.00
