title: reloadTimelineForComplication on watchOS 3
body: <p>In watchOS 2 when users make some activities in the Watch App we use reloadTimelineForComplication to reload the data in the complications. But in watchOS 3 it doesn't work. CLKComplicationServer find activeComplications, but when we call reloadTimelineForComplication nothing happens.
  How reload the data from the watchOS app in the complications now?</p>
