Mehdi Abaakouk f18d9fd7bd Don't call publisher without sample
Actually when you push samples into a pipeline, and the publishers don't
care of this sample, the publisher is called with a empty array of
samples.

This cause to send unuseful rpc/udp message.

With this change, the publisher is called only when it is needed.
