Fix repeatmasker bug

[BioWilko]

Repeatmasker names output files according to input filename (but trims .gz if present), patch to account for output file names being slightly different in this instance.

• This comment contains a description of changes (with reason).
• If you've fixed a bug or added code that should be tested, add tests!
• If you've added a new tool - have you followed the module conventions in the contribution docs
• If necessary, include test data in your PR.
• Remove all TODO statements.
• Emit the versions.yml file.
• Follow the naming conventions.
• Follow the parameters requirements.
• Follow the input/output options guidelines.
• Add a resource label
• Use BioConda and BioContainers if possible to fulfil software requirements.
• Ensure that the test works with either Docker / Singularity. Conda CI tests can be quite flaky:
  • For modules:
    • nf-core modules test <MODULE> --profile docker
    • nf-core modules test <MODULE> --profile singularity
    • nf-core modules test <MODULE> --profile conda
  • For subworkflows:
    • nf-core subworkflows test <SUBWORKFLOW> --profile docker
    • nf-core subworkflows test <SUBWORKFLOW> --profile singularity
    • nf-core subworkflows test <SUBWORKFLOW> --profile conda

Suggested change

	out_fasta = fasta.getBaseName(fasta.name.endsWith('.gz') ? 1 : 0)
	def out_fasta = fasta.getBaseName(fasta.name.endsWith('.gz') ? 1 : 0)

Thank you @BioWilko

Can we add a test to verify that this problem has been fixed? Perhaps a zipped input fasta?
