[issue19647] unittest.TestSuite consumes tests

[Stefan Holek]

New submission from Stefan Holek:

This test passed in Python <= 3.3 but fails in 3.4:

    def testTestSuiteConsumesTest(self):
        class MyTestCase(unittest.TestCase):
            def testMethod(self):
                pass
        test = MyTestCase('testMethod')
        suite = unittest.TestSuite((test,))
        result = unittest.TestResult()
        self.assertEqual(next(iter(suite)), test)
        suite.run(result)
        self.assertEqual(next(iter(suite)), test)

The suite contains None after it has been run in Python 3.4.
