RouteWayCostWorker: Fix recursive worker call

Since this method was run on `after_save` and in it
`RouteWayCostCalculator` calls `#update` on the given route, it caused
an infinite recursive call to the worker. To prevent this, wrap the
`#calculate!` call in methods that unset and reset the callback.
