Crash of the supervisor after returning {:stop, :normal, new_state}

[philipgiuliani]

Hi, I had a crash last which caused all my dynamic processes to die. I was able to find the same Exception in the following merge request: #174 .

From the logs I was able to understand that this crash happened after intentionally stopping one of the processes by returning {:stop, :normal, new_state}.
