Update test pipeline; we need to see errors
Update test pipeline; we need to see errors

The pipeline `transforms/csv-validations` includes `csv/branch-on-spec-version`,
which gets us to `process/process-v{3,5}-validations`, an async handler for
errors; we'd get nothing when calling `(all-errors errors-chan)`, and perhaps
pass the test when we should have failed.
