Fixes #344

There are no tests for non_differentiable as discussed in #252 . This does add a test here as it fits the criterion of either "add(ing) regression tests when we find issues with these rules / decide to add extra rules" but can just remove these tests if it's not wanted.

I don't think we need the tests (since we test the macro in ChainRulesCore), and the CI already takes ~35min.

Cool - I've removed the commit that added the tests (I was half expecting to do this anyway).

Now the changeset is just the Project.toml and adding the no diff rule.
