 `is_email()` returns the string on success, not `true`, so
 `test_returns_true_if_given_a_valid_email_address` isn't strictly
 accurate.

 I bring it up only after having wanted to use the `is_email()` tests
 during a demonstration as an example of a simpler unit test in core. I
 decided against it because I thought it might confuse someone that the
 test didn't use `assertTrue()`.
