fmhfunprofiler: fix test data and update snapshot

[nickp60]

PR checklist

I noticed that the previous test data was malformed, resulting in failure of one step of the tool; however the tool still outputs a file with a header, making it look like it was a success. Here I have fixed the tests as follows:

• changed the sourmash sketch to use the parameters described in the fmhfunprofiler readme (kmer sizes and using protein mode on the sarscov2 proteome)
• adjusted the test snapshot to capture actual content, not just the hash
• added tests for relevant minigut sample against both the full database and the test database.

Closes #12416

• 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.
• Broadcast software version numbers to topic: versions - See version_topics
• 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

I will change the path to the db in the tests from my personal once this PR for the data fix is reviewed and accepted.

Suggested change

	).match() }
	{ assert snapshot(
	path(process.out.csv[0][1]).readLines()[1..10]
	process.out.findAll { key, val -> key.startsWith('versions') }

every test should also capture the version output

Thank you Nick, agree with mashehu's requests etc but otherwise think this looks good. Thank you for detecting and fixing this!
