refactor(http-response): take url directly instead of request map

Response only ever reads the url out of the request array, so accept it
as a String directly. With url always present the 'url key missing'
LogicException can no longer fire, so Response::new and CurlResponse::new
return Self instead of a double Result. Also drops the unused
from_php_mixed/to_php_mixed stubs and the request_to_map helper.
