Bug 37591: Fix moredetail.tt performance issue

This patch fixes the performance issue in moredetail.tt by removing the
unnecessary call of checkout_renewals table.

To test:
1. Create lot of checkouts and renewals for a record.
2. Open the moredetail page for the record.
3. Check the timing of the page load.
4. Apply the patch and check the timing of the page load again.
5. The page load should be faster after applying the patch.
