Fix mistype which slipped through initial proof reading.
Remove usage of deprecated _scheme in Routing Component

Instead correctly use the array of schemes from the Route.
Also adjusted the dumpers to dump the correct data.

I extended the tests to not only test the deprecated behavior, but also
the new schemes-requirement.
