Bug 30512: Staff interface search results template error

This patch removes some markup from the search results template which
was causing markup to be output on the screen. Rather than correct the
markup so that the "p1" class is correctly added to the relevant links
I'm removing it. The "p1" class isn't used anywhere.

The patch also corrects two incorrect template filters on one of the
page's links.

To test, apply the patch and enable the following system preferences:

- AmazonCoverImages
- IntranetCoce (if available)
- LocalCoverImages

- Perform a catalog search in the staff interface which will return
  results with cover images from each of the enabled services.
- The covers should show correctly in the search results with no markup
  being output on screen.
