Bug 14605 - Corrects the individual fine's description

Bug 14605 - Corrects the individual fine's description

When paying a fine, the description is built out of the borrower's type and title, instead of the actual fine's description.

STEPS:
1) in the staff, go to a user with a fine to pay.
   a) if none, go to a user and Fines>>"Create manual invoice" with a
      distinctive description.
2) In Fines>>Pay fines, click the "Pay" button on the line of the fine.
3) This will take you a "Pay an individual fine" screen, where the description
   will look like "Staff Mrs", for the category and title of the borrower.
