Bug 11833 - fix filtering on saved report subgroup

Filtering the list of saved reports by subgroup doesn't work because the
filtering JavaScript was not updated when the table columns changed with
Bug 3134. This patch corrects the target column for filtering.

To test you must have multiple saved reports within one group, and at
least one of those in a subgroup.

- Apply the patch and go to Reports -> Use saved.
- Click the tab for the group which contains your reports.
- Choose the subgroup you want to filter on from the subgroup dropdown.

The list of reports should be correctly filtered by your subgroup.

NOTE: It seems weird to have the number of columns displayed change
      when filtered, but this patch does correct the filtering.
