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.
