Stream or StreamControllable both don't allow disconnect and reconnect #115
Description
As is designed right now, if if you try and do something like closing the stream controller call hubConnection.off(method) and then try and reconnect, this fails.
If you off a stream, it should reset everything and you should be able to on it again.
This means as written that there is no way to do things like stop a AI chat, then start it again later in the same session without completely resetting the HubConnection.
