Previously MediaStreamManager is not notified when a video capturing device has stopped due to error (e.g. the shared window is closed), so the notification UI is still shown when the stream already stopped.
This change fixes it by populating the state to MediaStreamManager through VideoCaptureHost --> VidoeCaptureManager --> MediaStreamProviderListner.
