This change updates the test command to use the fail explanation mode
by default. Since the test framework expects test rules to be
defined/true failure events are usually what is required to debug test
failures (e.g., some assertion in the test rule will Fail and that
will _likely_ be based on some failure in the policy under test.)
Hopefully this makes the test output a bit less verbose and more readable.
