Updated routeWithNavController to Ionic 4.

[chrisweight]

This is going to need to maintain backwards compatibility, so will need to account for the Ionic 3 paradigm too

[mreis1]

For backward compatibility you may want to try something like this:

(navController.setRoot || navController.navigateRoot)(match.$route, match.$args);
