This introduces assertion methods for unit tests that checks if some
code either emits a warning (assertWarns), or emits no warnings
(assertNoWarnings). This simplifies the work that's normally needed
(using warnings.catch_warnings()) to make basic warning testing
simple. It's mostly a port of Review Board's assert_warns.

Used this in other unit tests, which passed.
