Upgrade & fix break change in jsonschema

[parberge]

Followed the information from https://github.com/Stranger6667/jsonschema/blob/HEAD/MIGRATION.md#upgrading-from-025x-to-0260

I don't know if we have any tests that make sure we get validation error? If not maybe something that can be added. Not sure how though 😄
