Tagging this as semver-major because it turns a silent failure (?) into a thrown error.

If you assert on the error message instead of just the Error constructor, it gives us better detection of things like error message changes (which are semver major). It also verifies that we got the error we planned for.

The previous commit is a back-port of pull request nodejs#13821 to v6.x.
Its regression test does not apply to the v6.x branch (depends on
semver-major pull request nodejs#9405) so this commit adds a new test.
