Bug 37425: Check for existence of biblio object before fetching cover images
This patch simply adds a conditional to ensure the biblio object has been retrieved and assumes no cover images otherwise
To test:
1 - Enable system preference LocalCoverImages
2 - Perform a search in staff interface
3 - Find the biblionumebr for one of the results and delete it via the SQL backend:
DELETE FROM biblio WHERE biblionumber=3;
4 - Search again.
5 - KO!
Can't call method "cover_images" on an undefined value at /usr/share/koha/intranet/cgi-bin/catalogue/search.pl line 671.
6 - Reindex, confirm error is gone
7 - Apply patch
8 - Search again
9 - Delete a record from the results via SQL
10 - Reload and confirm no error
11 - Reindex and repeat search and confirm no error
