(DSL2) Pipeline fails when given a preindexed bwameth index

[TheodoreMarkulin]

Description of the bug

Pipeline fails when given a preindexed bwameth index. This is due to the Collect Software Versions step at the end of the bwameth.nf script. When provided an index, instead of allowing the pipeline to index the fasta, the version information is not available.

Steps to reproduce

Steps to reproduce the behaviour:

1. Create a bwameth index
2. Add this index to genomes availible to use.
3. Run pipeline with preindexed bwameth assets
