* Config_entry needs mac address for HA restart

    This was mistakenly taken out. Home-Assistant needs to store mac address in
    case restarted. TV needs to be on to acquire mac address. This is neccesary
    to allow TV to be turned on by Home-Assistant after Home-Assistant is
    restarted.

* Skip update() during state changes

    It is best for performance to skip updates during state change because
    bravia.turn_on() will commonly push async_update() beyond it's update
    interval.

* update tests
