[release/1.4.4] event: fixed subscribtions to stopped event mux
This fixes an issue where the following would lead to a panic due to a
channel being closed twice:
* Start mux
* Stop mux
* Sub to mux
* Unsub
This is fixed by setting the subscriptions status to closed resulting in
the Unsubscribe to ignore the request when called.
