workflow_test_init incorrect run from invocation

outcome of `planemo workflow_test_init --from_invocation`

The workflow has 4 inputs, 2 fastas and 2 tabular files.

Maybe the fact there are spaces in the input names is causing the duplication here?

Start by reproducing `planemo workflow_test_init --from_invocation` and inspect the generated `test-data` entries, especially the FASTA and tabular files whose names contain spaces. Compare the generated inputs with the four workflow inputs and verify that each file is included once with the correct mapping. The issue does not identify a source file or test to run.
