Title: Actually fix unescaping of proxy auth credentials

- The current way is broken as it chokes while unescaping characters that are not allowed non-escaped in the userinfo URI component, such as "@" if the username is an email address.
- Being a nice Ruby citizen means not mutating the `@proxy_uri` which is an object that might have come from the user.
