Workflow upload failure: family_name/orcid has already been taken

[hexylena]

Describe the bug

When uploading an RO-Crate I'm seeing the following error message:

{"errors":[{"source":{"pointer":"/data/relationships/assets_creators"},"detail":"orcid has already been taken"},{"source":{"pointer":"/data/relationships/assets_creators"},"detail":"family_name has already been taken"},{"source":{"pointer":"/data/relationships/assets_creators"},"detail":"family_name has already been taken"}]}

This only occurs when I have creator information in the ro-crate-metadata.json and the workflow.ga file. If i remove the metadata from the workflow.ga, then it can be uploaded.

To Reproduce

Steps to reproduce the behavior:

1. POST the ro-crate from slack to /workflows/submit

Expected behavior

It uploads
