fix truncation of results in phased queries where checkAminoAcidChange=TRUE

[julie-sullivan]

Please see Todd's document for a full description of the bug, but here is a summary:

1. example query input: 1:100:A:G with parameters: checkAminoAcidChange = true, ignorePhase=false
2. HGVS value is used to query results not the variant coordinates e.g. p.Met1?
3. Query results may include more than one variant matching p.Met1?: 4. e.g. 1:100:A:G (3 trait associations) 1:101:A:G (2 trait associations) 1:101:T:C (7 trait associations)
4. code picks the first result and ignores the rest.

Also we have a unit test but it uses mockito. Do you want it anyway?

15:90766924:T:G,15:90766927:G:T were the original problematic variants.
