Need to improve template weather sensor logic

[thejeffreystone]

Need logic to handle the event when weather sensors have not returned any data from weather API. Should just be able to wrap this logic to test if states.weather.klzu_daynight.state == 'unavailable' that way the error below doesn't fill my log file.
