Manually added contributor without ORCId is exported as ORCID = null

[ValentinFutterer]

Describe the bug
A manually added contributor without an ORCID is exported like this

And on a sidenote, it says ORCID iD, with a lowercase i and highercase D. It should probably say just ORCID.

Is this a regression?
Yes.

Expected behavior
It should not show the ORCID at all, when none is given through the frontend.

Environment

• Damap version 4.3.1
