demonstrate multi-allelic gVCF failure - test added

[jpdna]

This PR does not pass tests - this is as intended as purpose is to demonstrate problem.

Test added in ADAMContextSuite
and related test vcf file, which demonstrates that we currently cannot import gVCF variants which have a
Multi-allelic site with non-ref symbolic allele

error reported when running tests is:
