Title: Unsubscribe connection from channels on close_connection

I had performance issue in my project - when i open a web-page where users subscribes to some websocket channel and press refresh several times, Channel.subscribers start to grow. Then when i send server message to channel it takes a lot of time to notify all subscribers which are already disconnected.
