Bug 37859: Fix style of tabs on comment review page

This patch corrects the tab markup on the comment review page. These
tabs are just links styled as tabs -- there isn't any JS tab swapping.
This kind of "static" tab markup wasn't handled by the tabs WRAPPER
work.

To test you should have some comments data in your system:

 - Go to Administration -> System preferences and enable the
   "OPACComments" preference.
 - Log in to the OPAC and search for a bibliographic record.
 - View the detail page for the record and click the "Comments" tab.
 - Click "Post your comments on this title."
 - Enter some text in the review box and submit.

In the staff interface, go to Tools -> Comments.

 - You should see two tabs: "Approved comments" and "Comments awaiting
   moderation."
 - Confirm that the tabs look correct.
 - Approve one or more comments and confirm that the tabs work correctly
   to switch views.
