Fix meta ID in tests to match new test data file names

[mathiasbio]

Description

In the current subworkflow tests for generate cytosure and preprocess_snvs we are setting metadata IDs to "SNV" which is no longer correct, and should now be "subject_a" to match the new filenames.

How to reproduce

Check here: https://github.com/Clinical-Genomics/oncorefiner/blob/dev/subworkflows/local/process_snvs/tests/main.nf.test

The parsing of the VCF name here in "main.nf"

ch_snv_vcf              = channel.fromPath(val_snv_vcf).map { vcf -> [[id:vcf.simpleName], vcf] }.collect()
ch_snv_vcf_tbi          = channel.fromPath(val_snv_vcf + '.tbi', checkIfExists: true).map { vcf -> [[id:vcf.simpleName], vcf] }.collect()

Takes the first string before the "." which is subject_a

But I'm not sure how to think about these IDs in the test, if it is important to match the names exactly as they are in our pipeline-test, since these tests are supposed to be insular and shareable, and this logic in the main.nf is part of our specific logic in oncorefiner. I'm confused!

I would not say that this is important. They should not have to be tied to the pipeline tests at all.
