Dynamic Routing Beta: StaticRoutesRouter has to respect the route name

refs #9601

- this was already working for collections or channels
- but the `routeName` was not parsed for static routes
- ensure we push the route name into the context object

e.g. /about/: about

-> name of the route is "about"
