Omim fix

Two fixes related to disease page and OMIM external API
- fix wrong links to OMIM page from human orthologs in the tables on Disease page
- reduce number of requests to OMIM API by combining multiple requests into one. This should reduce the frequency of our requests being rejected by OMIM API - noticed this problem on disease pages with many used as its models.
