Zack Tanner 9854c342e1 #5620: Fix react-i18next example to properly SSR (#5265)
This fixes https://github.com/zeit/next.js/issues/5260 by making sure that `index.js` has `getInitialProps` defined on the page exported component, not the child component.

When fixing that, I uncovered an issue where the server side rendered HTML did not match the clientside HTML, so I reworked _app.js to use the `i18nextprovider` component which has props to hydrate the initial data (for SSR), and makes sure the correct i18n instance is passed to all child components through context.

Before:
```html
<!DOCTYPE html>
<html>
   <head>
      <meta charSet="utf-8" class="next-head"/>
      <link rel="preload" href="/_next/static/development/pages/index.js" as="script"/>
      <link rel="preload" href="/_next/static/development/pages/_app.js" as="script"/>
      <link rel="preload" href="/_next/static/development/pages/_error.js" as="script"/>
      <link rel="preload" href="/_next/static/runtime/webpack.js" as="script"/>
      <link rel="preload" href="/_next/static/runtime/main.js" as="script"/>
   </head>
   <body>
      <div id="__next"></div>
      <script src="/_next/static/development/dll/dll_4a2ab6ce0cb456fbfead.js"></script><script>__NEXT_DATA__ = {"props":{"pageProps":{}},"page":"/","pathname":"/","query":{},"buildId":"development"};__NEXT_LOADED_PAGES__=[];__NEXT_REGISTER_PAGE=function(r,f){__NEXT_LOADED_PAGES__.push([r, f])}</script><script async="" id="__NEXT_PAGE__/" src="/_next/static/development/pages/index.js"></script><script async="" id="__NEXT_PAGE__/_app" src="/_next/static/development/pages/_app.js"></script><script async="" id="__NEXT_PAGE__/_error" src="/_next/static/development/pages/_error.js"></script><script src="/_next/static/runtime/webpack.js" async=""></script><script src="/_next/static/runtime/main.js" async=""></script>
   </body>
</html>
```

After: 
```html

      <link rel="preload" href="/_next/static/runtime/main.js" as="script"/>
   </head>
   <body>
      <div id="__next">
