fix: Update URL resolution logic to handle search parameters on root path /?foo=bar

[F7b5]

What?

This PR fixes and implements test for an URL resolution issue that stripped the searchparam when metadataBase was defined and a search param was set on the root path. This created a behavior where :

export const metadata: Metadata = {
  title: "Create Next App",
  description: "Generated by create next app",
  metadataBase: new URL("https://www.example.com"),
  alternates: {
    canonical: "/?foo=bar",
  },
};

would result in

<link rel="canonical" href="https://www.example.com">

instead of

<link rel="canonical" href="https://www.example.com/?foo=bar">
