Problem/Motivation
NodeRouteProvider does not extend DefaultHtmlRouteProvider. Thus, it contains duplicated logic.
Proposed resolution
Make NodeRouteProvider extend DefaultHtmlRouteProvider.
Remaining tasks
Review.
User interface changes
None.
API changes
If someone has a route provider that extends NodeRouteProvider and has e.g. a getCanonicalRoute() with different parameters than DefaultHtmlRouteProvider this could break. I think that is something we can get away with in a minor version but I guess we could write a change notice to be nice.
Data model changes
None.
