Unable to use fix without antitarget file for WGS samples

[GACGAMA]

Hello

This is related to #242

It seems like the newest version contains some old bugs for some reason

When trying to generate .cnr files with fix command without antitarget for whole-genomes:

cnvkit.py fix /scratch4/nsobrei2/ggama1/somatic_SVs/cnvkit/call_genomes/BH10027_1_TUMOR.targetcoverage.cnn /scratch4/nsobrei2/ggama1/somatic_SVs/cnvkit/needed_files/genomes_reference.cnn -o /scratch4/nsobrei2/ggama1/somatic_SVs/cnvkit/call_genomes/BH10027_1_TUMOR.cnr

I get:
cnvkit.py fix: error: the following arguments are required: reference

If I create a decoy empty file antitarget, as proposed on older version, I get:

Blank tab file?: /scratch4/nsobrei2/ggama1/somatic_SVs/cnvkit/call_genomes/BH10027_1_TUMOR.antitargetcoverage.cnn
Processing target: BH10027_1_TUMOR

When processing with batch, using the same reference, everything works fine.
