async void with unhandled exception in WebSocketTransportDuplexSessionChannel.cs

**Describe the bug**
I don't have a way of reproducing it, but I found it by looking at the code.
In file: wcf/src/System.Private.ServiceModel/src/System/ServiceModel/Channels/WebSocketTransportDuplexSessionChannel.cs you have a a class WebSocketMessageSource that has a method:
`async void StartNextReceiveAsync()`

it has an exception being thrown:
`if (currentState != AsyncReceiveState.Finished)
{
throw FxTrace.Exception.AsError(new InvalidOperationException());
}`

In the case of this exception, aren't we crashing the process?
