Bug 33278: Correct JS for activating default tab on various pages

The conversion of the header search tabs to Bootstrap resulted in a bug
on several staff interface pages: The first tab isn't selected by
default. The jQuery selector isn't specific enough.

The patch also corrects a template error which was introduced to
merge-record.inc by Bug 32683.

To test, apply the patch and test the following pages to confirm that
the first tab on each page is selected by default:

- Catalog -> Advanced search
- Catalog -> MARC details
- Catalog -> Search results -> Merge
- Administration -> Authorized values -> Edit
- Administratoin -> Library transfer limits
- Administration -> Item types -> Edit
- Authorities -> Authority details
- Authorities -> Search -> Merge
