Remove unused react-rails gem

The connection_pool gem changed their API, which caused a breakage in our react-rails gem.

It turns out though, we're not actually using react-rails anymore. It's primarily for React server-side rendering, which we don't do. Our React code is bundled as normal Javascript via our usual asset pipeline.

So, to resolve the gem incompatibility, we remove react-rails altogether. Neat!
