Bump version to 4.0.4

Remove unsetting of device_queue_item.
In case the queue-item does fit the first RX window, but not the second one, it will be set to None. If this happens, then the save_downlink_frame step will not add the queue-item ID to the DownlinkFrame (internal). Then on txack, ChirpStack is unable to dequeue the payload causing the payload to stay in the queue.
