The module is not reported correctly on handled records

I noticed this issue while working on the QueueHandler.

The following test succeeds with CPython logging but fails with picologging:

def test_queue_handler_dispatch():
    logger = picologging.Logger("test", picologging.DEBUG)
    q = queue.Queue()
    handler = QueueHandler(q)
    logger.addHandler(handler)
    logger.debug("test")
    record = q.get(block=False)
    assert record.module == "test_queuehandler"

In picologging, the module is reported as simply "python" instead. I haven't dug in yet to see where the problem is.

Start with the test_queue_handler_dispatch example and the QueueHandler path, then compare how picologging and CPython logging determine the record module. Run the test to reproduce the failure; done means the queued record reports "test_queuehandler" instead of "python".
