Prerender generates wrong path for routes from routesFile if baseHref contains host

[constantant]

Which @angular/* package(s) are the source of the bug?

router, Don't known / other

Is this a regression?

Yes

Description

I try to prerender a web app which uses CDN for the static files so document.baseURI and APP_BASE_HREF are different and document.baseURI looks like https://aws-blablabla.com/version-0001/build-0002/.

For the discovered routes everything works fine but if I need to indicate the dynamic ones it generates the wrong path like https:/ aws-blablabla.com/ version-0001/ build-0002/ dynamic/ path/ 01/ but it must be dynamic/ path/ 01/

Please provide the environment you discovered this bug in (run ng version)
