Bug 25846: (follow-up) Show "No cover image available" message

This patch restores the use of a "No cover image available" message in
staff interface search results when no cover image was found by any
image service.

The patch also corrects markup in the search results template which was
preventing the "Adlibris cover image" text from being correctly hidden.
