Bug 36708: Fix column index for processing No automatic renewal after

Bug 36708: Fix column index for processing No automatic renewal after

To test:
1- Find or create a circulation rule with a 'Holds allowed (total)' limit of 3 (or another number) and no value in 'No automatic renewal after (hard limit)'
2- Select to edit the rule, and note that 'No automatic renewal after (hard limit)' box in the editing line is now populated with a date
3- Note also that 'Holds allowed (total)' is empty in your editing line
4- If you save your edits without clearing the new 'No automatic renewal after (hard limit)' date, it will save as part of the rule. Also, 'Holds allowed (total)' will save as Unlimited unless you re-add your numerical value.
5- APPLY PATCH
6- Try again, the values should save corrected and not erroneously fill the No automatic renewal after (hard limit) column.
