Unititialized attribute makes the protocol hang forever #644
Description
When implementing a new protocol in Onet I forgot to initialize the chan that sends back the response to the service. In this case, I would expect the service and/or protocol to fail and output an error, but it just waits forever.
How to reproduce
Clone the cothority_template, in protocol/protocol.go remove line 43 ChildCount: make(chan int),. Then, launch the protocol's or service's tests. The tests will just hang.
