schema after migrations

[djarecka]

I've fixed some issues with the reproschema migrate and this is what I got running it for the activities.

@satra @ibevers - let me know what you think

It looks good after a cursory inspection, although I probably don't have a deep enough understanding of the version changes to notice more subtle issues.

@djarecka this one migrate the old version to our new pydantic model generated version, right?

GA failed this part, I guess it's because our new version uses id instead of @id

Traceback (most recent call last):
  File "tests/jsonParser.py", line 12, in <module>
    if data["@id"] and data["@id"] != name:
KeyError: '@id'
