Failing tests

[kathryn-ods]

Some of our tests are failing again and I can't figure out why - they are failing on branches that were passing last week with no changes since. Possibly an issue with the tests themselves.

James please could you have a look when you're back from annual leave?

• 3.0 was working last week - https://github.com/openreferral/specification/tree/3.0
• small changes to 3.0 docs - https://github.com/openreferral/specification/tree/3.0-warning-box
• tiny change to 3.1 - Update LICENSE #544
