Fix for selection handles.

Selection handles may remain pressed after the power button is pressed.

* The TouchEvent with Interrupt state is not handled.
  Actually Dali core does not send this event when the power button
  is pressed. This patch is a work-around to fix the issue.
  Would be a proper solution send the TouchEvent with the Interrupt
  state when the power button is pressed?
