Port error handling tests to cljc

[WilliamParker]

I propose that it makes sense to have a .cljc namespace using def-rules-test that is specific to tests of error handling. IMO test-rules.clj has grown overly large and we should refactor it into multiple namespaces by the functionality under test as part of our uplift after #296. This would currently include tests for changes like

• Provide better feedback when constraints throw exceptions #255
• Catch and re-throw exceptions on rule right-hand sides with more information #147

In the future it could include tests for changes like

• Add error handling of exception thrown during accumulation #265
• Throw exception on suspected infinite loop scenarios #275
