Make production build works by opt-out static build for search pages

[MrOrz]

Currently staging build fail because /search page is using a runtime config.

According to next.js doc:

A page that relies on publicRuntimeConfig must use getInitialProps to opt-out of Automatic Static Optimization. Runtime configuration won't be available to any page (or component in a page) without getInitialProps.

We should pass {ssr: true} to withApollo so that next-apollo attaches getInitialProps to search page and thus opt-out Automatic Static Optimization for /search page.
