When converting an `http::Request` from `hyper` to an `http_types::Request` the `url` fails to convert with an error: ```rust relative URL without a base ``` small example problem showing the failure: ```rust use std::convert::TryFrom; fn main() { let request = http::Request::builder() .method("GET") .uri("/") .header("Host", "localhost") .body(http_types::Body::empty()) .unwrap(); http_types::Request::try_from(request).unwrap(); } ```
