Empty VCF file fails in genmod score

[fa2k]

Description of the bug

This is arguably a problem with genmod and there is a bug report Clinical-Genomics/genmod#130, but I hope you don't mind that I report it here.

If the input VCF file to genmod score is empty, the process crashes. I get this problem with the structural variants file in NFCORE_RAREDISEASE:RAREDISEASE:RANK_VARIANTS_SV:GENMOD_SCORE.

We can close the bug if it gets fixed in genmod, or maybe there's a way to prevent it from running genmod if there are no variants.

Maybe there will never be zero SVs in real genome data. I have an error with svdb that caused the empty file in my case. I will close this one as I think it's not really a problem, and instead report an issue about svdb / gnomAD.
