A DependencyContainer extension has been added to the testing target
in order to ensure that all interfaces registered in the container
have been swapped for Mock classes instead.

Also, a RouterMock implementing Router spy methods and all Routes is 
used to test all routes are executing the correct flow using the correct
transition.

Finally, a RoutesMock which implements all Routes interfaces has been
added to ensure all routes being triggered from the view models are
properly tested.
