Summary:
When calling -[MKDirections calculateDirectionsWithCompletionHandler:], the MKRouteStep objects returned in the route response are missing instructions.

Steps to Reproduce:
Run the following code:

    MKPlacemark *sourcePlacemark = [[MKPlacemark alloc] initWithCoordinate:CLLocationCoordinate2DMake(37.8, -122.4) addressDictionary:nil];
    MKPlacemark *destinationPlacemark = [[MKPlacemark alloc] initWithCoordinate:CLLocationCoordinate2DMake(37.7, -122.4) addressDictionary:nil];

    MKDirectionsRequest *directionsRequest = [[MKDirectionsRequest alloc] init];
    directionsRequest.source = [[MKMapItem alloc] initWithPlacemark:sourcePlacemark];
    directionsRequest.destination = [[MKMapItem alloc] initWithPlacemark:destinationPlacemark];

    MKDirections *directions = [[MKDirections alloc] initWithRequest:directionsRequest];
    [directions calculateDirectionsWithCompletionHandler:^(MKDirectionsResponse *response, NSError * error) {
        MKRoute *firstRoute = [response.routes firstObject];
        for (MKRouteStep *step in  firstRoute.steps) {
            NSLog(@"Instructions: %@", step.instructions);
        }
    }];
