Replace stack about ex-navigation

[Froelund]

Nevermind - I figured it out.
I was actually on the right path ( Or route :) ).
immediatelyResetStack takes a second parameter index. This defines where on the new stack, you would like to end up.
So the code would be:

this.props.navigator.immediatelyResetStack([
    Router.getRoute('routeA'), Router.getRoute('routeC', {routeCSpecificProp: this.props.routeCSpecificProp}))
], 1); // Notice the 1

Just to clarify if someone stumbles upon this issue. Instead of creating a new stack, you should reuse the one that are already made.

      var stackOfRoutes = this.props.navigator._getNavigatorState().routes;
      var newRoutesStack = [stackOfRoutes[0], stackOfRoutes[2]];
      this.props.navigator.immediatelyResetStack(newRoutesStack, 1);
