Add functionality to refresh the navigator when route state is changed or some other overriding feature

[bambinoua]

Sometimes it is necessary to refresh the current route which has the same location (see issue #512). I tried your suggestion but it did not work for me because method _runGuards returns true for a BeamGuard which returns a specific BeamLocation and method update exits before it calls notifyListeners.

I investigated the method apply of BeamGuad and it always returns true if

if( redirectionBeamLocation.state.routeInformaiton.location 
  != target.state.routeInformation.location) {
  return true;
}

It would be good if this condition also included routeInformation.state check. Or maybe some parameter of BeamGuard with signature bool Function(context,origin,target) which can be used in above mentioned condition.

@bambinoua Indeed, it should also check RouteInformation.state

We have a problem with including a state check because you cannot really define the state if using BeamGuard.beamToNamed. This will be reworked as a part of v2 which will focus on guards.
