Refs: #3297

- fix of RouteObserver#after_destroy (dead code right now, but see below)
- change specs to use Route#destroy in order to trigger `dependent: :destroy' in stop_points
   (#delete does not work as stop_points is used in `has_many :stop_areas, through:', no doc found on this behavior, but #destroy is the advocated method to be used)
