This commit does away with all the old manual message equality tests and replace it with a single property-based test that uses the testing/quick package. This test uses a single scenario which MUST hold for all the messages type and all possible messages generated for those types. As a result we are able to do away with all the prior manually generated test data as the fuzzer to scan the input space looking for a message that violates the scenario.
