Span is missing for those nodes that don't trigger the onComplete event

[sergimola]

Those nodes that don't trigger the onComplete event don't have a span.

I've seen it happening in those nodes that receive a network call and start a new Message, such as the tcp in node.
The http in also has the same behaviour (not triggering the onComplete event), but there is some code to handle it explicitly.
Another example of this problem is the server-events from node-red-contrib-home-assistant-websocket.

It can be easily reproduced with the following flow.

    }
]

You'll get this: (only the parent span, not the child span)

Thanks for reporting this from #9 (comment)
I will search a workaround for these nodes, maybe using the postReceive event but I didn't use it because it broke some other node span.

I create issue node-red/node-red#5011 on Node-RED repo, may be it should be fixed on the core.
