fmh-funprofiler silent errors

Have you checked the docs?

Description of the bug

Both the test database I created in nf-core/test-datasets and the test data used here for fmh-funprofiler are formatted incorrectly but the tool doesn't raise a proper error. One of the two issues is fixed here, and will be working on figuring out whats wrong with the db in test-datasets asap. Just wanted to raise the warning here in case anyone else notices the issue.
