[noPoll] nopoll_conn_set_on_ready don't work as expected

[Francis Brosnan Blázquez]

Hello Elmar,

Certainly you have found a bug. I've updated noPoll's source code to
allow defining on_ready handlers at client side...which will be called
once handshake is completed.

https://github.com/ASPLes/nopoll/commit/f1d3f5151c176f0f6af80cf671cbf611c2605d4c

We should be close to release next stable release (I hope this week),
Best Regards,
