Session.close: Call close handler on websocket close

Browse Source 
When scratch closes websocket connection, bluepy-scratch-link does not
close Bluetooth connection cleanly. This causes connection failure on
reconnect.

To close Bluetooth connection, catch ConnectionClosedError of websocket
and call close handler of the session.
