docs: Deselects all dates on the current calendar.
  @method deselectAll
  @return {Date[]}  Array of JavaScript Date objects representing all individual dates that are currently selected.
  Assuming that this function executes properly, the return value should be an empty array.
  However, the empty array is returned for the sake of being able to check the selection status
  of the calendar.
