Do consume messages on the correct thread after resume

[hadadil]

Motivation:

In our code we do pause the consumer and later resume it. something as below

consumer.pause();
Uni<Void> processing = ....
processing
.eventually(consumer::resume)
.subscribe()
.with(UniHelper.NOOP);

when we call resume the next msg processed on event loop regardless the consumption meant to be on worker thread based on the Verticle deployment.

Recently message consumer implementation message delivery has been reimplemented using the new inbound message channel utility. This concern has been added as a test 59f8f98

@hadadil thanks for raising this concern, your test has been integrated and your initial review triggered the reimplementation of message consumer using the inbound message channel we developed and got rid of custom code

@vietj thanks for the information.
good to hear that this behavior was already fixed on version 5.0.0 and it's more wonderful now it's covered with a test.
Cheers!
