Bug 10954: ensure that payment receipt displays the payment made

Bug 10954: ensure that payment receipt displays the payment made

When printing a payment receipt, the payment did not display, only the
total currently owed.

Test Plan:
1) Create a payment for a borrower
2) Print the payment with the "print" button to the right of the payment
3) Note the missing payment line
4) Apply this patch
5) Repeat step 2
6) Note the payment line now displays
