createTimer property is invalid

[steveandroulakis]

Could you please update the demo for the Timer API to reflect the docs? It fails to run in its current state.

The timer demo uses 'label' as the property. https://github.com/alexa/alexa-cookbook/blob/00bbec4f0c07d223b58be5b335dfcd842c6f9a03/feature-demos/skill-demo-timers/lambda/index.js#L18

This didn't work (Alexa gives a 500 error).

The docs say 'timerLabel' as the property. https://developer.amazon.com/en-US/docs/alexa/smapi/alexa-timers-api-reference.html#create-a-timer-operation-announce

Changing the property to 'timerLabel' worked.

e.g. timerLabel: handlerInput.t('ANNOUNCEMENT_TIMER_TITLE_MSG')

Thanks, Steve
