Investigate duplicate SV calls.

[bpblanken]

I found duplicate rows in our SV tables, I was able to track down duplicate rows with the same variant id but different annotations in the original callset:

chr1	166994963	cohort_2911.chr1.final_cleanup_DEL_chr1_9621	N	<DEL>	68	PASS	AC=53;AF=0.006828;ALGORITHMS=wham;AN=7762;
chr1	166994997	cohort_2911.chr1.final_cleanup_DEL_chr1_9621	N	<DEL>	551	PASS	AC=73;AF=0.009405;ALGORITHMS=wham;AN=7762;

Investigate further.
