Fix loading of `Services` module in production
Fix loading of `Services` module in production

By default, code in `/lib` isn't loaded by Sidekiq in production,
because sidekiq has disabled autoloading for reasons of thread-safety.
This means we have to explicitly tell Rails to eager load things in the
`/lib` directory when booting up.
