This fixes two edge cases in the url generator:
1. when the context scheme is not known (empty) generating an absolute url would return an invalid url starting with `://host/path`. #25491 handled the case when the host is unknown which makes sense. but the way it was done, created this new problem.
2. non-http(s) urls do not require a host. e.g. typical `file:///path` urls. url generator is fixed to be in line with rfc3986
