Bug 26721: Fix permission check on debit and credit type admin pages

Bug 26721: Fix permission check on debit and credit type admin pages

At the moment the pages falsely check for parameters_remaining_permissions,
but they should check the specific manage_accounts permission.

To test:
- Create a new staff user with only catalog and manage_acccounts
  permissions
- Log in with this staff user and go to the admin page
- You will see the debit and credit type sections, but won't be
  able to access them
- Apply the patch
- Veriy the links still show, but pages are now accessible
