Attempt to fix closeclick issue in InfoWindow

- propagate google maps InfoWindow's closeclick event to the parent component
  however, re-open the InfoWindow to ensure, its state is set solely by
  the opened prop of the InfoWindow component
- do not emit closeclick in the _openInfoWindow() method triggered by
  the watcher on the opened prop. closeclick should only be triggered,
  when the user atually clicked close
