Bug 7472 Edit button ineffective when paying borrower fee

On payment page, the Edit button doesn't load anymore the current
borrower edit page.

To reproduce the bug:

- Define a borrower category 'foo' with Enrollment fee
- Create a new 'foo' borrower
- Click on Check out tab
- A message is displayed: Fees & Charges: Patron has Outstanding fees &
  charges of xx.00. Checkouts are BLOCKED because fine balance is OVER
  THE LIMIT. Make Payment
- Click on Payment link
- Click on Edit button
- You reach a page for creating a new borrower
  => you should reach the current borrower edition page

- Same issue on paycollect.tt template
