This converts existing "preparser" tests that expect a certain exception message to be produced into "message" tests. Thereby we get much better coverage because the former test suite degraded by now to just check whether each test case threw or not, the exception message was not being checked at all. This also deprecates the ability of "preparser" to specify that single test cases based on JS files are expected to throw, "messages" is far superior, use that test suite instead.
