Human CFTR does not show up when searching for cystic fibrosis

[kshefchek]

I thought at first it was related to #214, but it turns out this is because gene definitions are fetched on the client/browser by querying mygene, so these do not make it into solr. Cystic fibrosis does not appear in the solr document at any other point (ie synonym), https://solr-dev.monarchinitiative.org/solr/search/select/?q=*:*&fq=id:%22HGNC:1884%22&wt=json

possible solutions:

1. ingest gene definitions in dipper
2. ingest gene definitions when loading solr search

Looking at this closer, it looks like we only index synonyms on the clique leader id, but not those on equivalent Ids, which have additional synonyms, see
https://api-dev.monarchinitiative.org/api/graph/edges/from/HGNC:1884?relationship_type=equivalentClass

If we were to index the synonyms from equivalent ids then we would get CFTR when searching for cystic fibrosis.

Relocating this to the solr loader

Reopening on the UI side since this is still an issue, another example is BRCA1 and breast cancer

[kshefchek]

I added synonyms of equivalent terms to our search index with SciGraph/golr-loader@ef14285

This adds labels that should help with this issue, for example:
CFTR: cystic fibrosis transmembrane conductance regulator

BRCA1: breast cancer type 1 susceptibility protein

However, this hasn't entirely helped
