[i18n + redirects] defaultLocale not stripped from destination url

[wadehammes]

Bug report

Describe the bug

When creating a redirect:

module.exports = {
  i18n: {
    locales: ["en", "es"],
    defaultLocale: "en",
  },
  async redirects() {
    return [
      {
        source: "/about",
        destination: "/about/our-story",
        permanent: false,
      },
    ];
  },
};

The redirect happens fine, however the destination URL in the browser is /en/about/our-story which is not great since this will break SEO.

Adding locale: false makes the redirect not happen at all.

To further add, logging out router on this page actually shows asPath as /about/our-story even though the path clearly has en in it.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. Have internalization set up with next.config.js setup like above
2. Create a redirect

Expected behavior

defaultLocale should not be present in the url, as with all other non-redirected links.

System information

• Browser (if applies): Edge
• Version of Next.js: 10.0.3

Anything on this? Would love some insight into if this is a problem with my setup or a problem with Next.js. Looks like this will be solved in #19766
