Store scenario patch

[GiPe66]

Hi William,

I have successfully made store scenario working. Please replace the commented out part of mqtt_client.py with the following block.

`
Sorry, code indentation does not work...

    elif ('set_scenario' in str(topic)):
        print('Incoming MQTT set_scenario request : ', topic, payload)
        get_id = (topic.split("/"))[2] #extract id from mqtt
        print(str(get_id), 'run scenario')
        if not self.tydom.connection.open:
            print('Websocket not opened, reconnect...')
            await self.tydom.connect()
            await self.tydom.put_scenarios(str(get_id))

        else:
            await self.tydom.put_scenarios(str(get_id))

`
Thanks for all. Jean-Paul.
