Bug 35015: Adjust column index in fnFilter

This patch fixes the column index in the call to fnFilter following the
addition of a new column to the table in bug 32341

Test plan:
1) Add some charges to a patron account
2) Pay some of these charges so that they are no longer outstanding
3) In the OPAC log in as that patron and navigate to the Charges tab in
   their account
4) Observe that all charges are listed, even if they have been paid and
   clicking the Show all transactions button has no effect even if
   clicked multiple times between the different filtering options
5) Apply patch
6) Refresh page and now the settled charges should be filtered out
7) Click the Show all transactions button and it should correctly update
