Corrected reference to assertMultiLineEqual method on unittest.TestCase.

The setUp method on FunctionalTest was adding a type equality function
for str. Instead of returning a reference to the TestCase.assertMultiLineEqual
method it was returning the string 'assertMultiLineEqual'. This caused
any test that used self.assertEqual(str, str) to throw an exception
as the string was not callable.
