fetchState not working if component uses contextTypes

I tried using `react-router-server` in a project that uses `react-intl`. In some components I need to use the intl context that is provided by `react-intl` but if I declare contextTypes for that component fetchState doesn't work.

I added console.log statements to the callback of my data fetch method and the callback of renderToString and it seems like the component just ignores that it should fetch data and renders immediately.

Start by reproducing the issue in a project using react-router-server with react-intl, focusing on a component that declares contextTypes. Compare the data-fetch callback with the renderToString callback and determine why rendering proceeds before fetching; done means fetchState works while the component consumes the intl context.
