tests: use context manager form of assertRaises Support for using unittest.TestCase.assertRaises as a context manager was added in Python 2.7. This form is more readable, especially for complex tests. While I was here, I also restored the use of assertRaisesRegexp, which was removed in c6921568cd20 for Python 2.6 compatibility.
