Bug 35557: Remove LoadResultsCovers

Bug 35557: Remove LoadResultsCovers

The JS function LoadResultsCovers is not used from the Staff interface.

It is supposed to load the local cover images in JS but actually we are embedding the thumbnail in the img tag.

Test plan:
Confirm that LoadResultsCovers was called but had no effect.
Note that the selector ^local-thumbnail only exists in shelfbrowser.inc

but results.js is only used from results.tt (not shelfbrowser.inc)
