Fix fetching apolloState on SSR

• Convert Class to Function component
• Add types to withApollo() and the other functions

It's still rendering the loading state in SSR, but all the apolloState is being passed correctly now:

The problem with the loading state is because of the beta versions of @apollo/* we're using:
