Remove path prefix

[georgeboot]

Our server is configured as follows: `https://domain.com/api/v1'
However, this package seems to simply take the uri's from the route and use them as paths.

That means that the openapi document now contains operations for api/v1/blog/{blog} whereas it should have been blog/{blog}.

It feels to me the package should instead generate full url's for routes, and remove the server url prefix from them.
