QueueListenerTest of test_logging now closes the multiprocessing
Queue and joins its thread to prevent leaking dangling threads to
following tests.

Add also @support.reap_threads to detect earlier if a test leaks
threads (and try to "cleanup" these threads).

On AppVeyor, before this change test_logging failed (env changed) with "Warning -- threading._dangling was modified by test_logging", after this change the test now passes ("test_logging passed")!
