Add variant_set_id when returning GenomicShortVariant
The id of the variants comes in the following form:
```python
'55e945ec-57d1-4dde-9a59-bcdd6d7271e6:+0LLoDMx2dXBmvef9GcN4Dz+v4EMI87/FXW9X2mG72k=:TFB2M'
```

The first part of this ID is the variant_set_id which can be joined with the output of the `GenomicTest` to match a given mutation to the patient. This is a common use case.
