Additional unit test for audit.js: failure cases and logging examples.

The unit test for audit.js only covers basic/successful cases.
This CL is to add another unit test that tests failure cases with the
expected text result.

In the course of refining the failure output message, some editorial
edits also have been made in audit.js.
