Fix blastp hit link

* #2950
* added blastp test to protein

Link to test: /species/b_malayi/protein/BM:BM25559#3--10

Bug: on the live site (http://www.wormbase.org/species/b_malayi/protein/BM:BM25559#3--10), clicking on 'RP:RP47323' in the table would redirect to 'search/all' when it should link directly to the protein page. Problem was in the class returned in the hash.
