put config stuff in correct directory

Right now you're dropping things in `app/config`, which I believe is incorrect. This should fix that and put them in just `config` with everything else.

This lead to a weird bug where we had overridden the gem's initializer in the normal config directory, but there was still a generated one hiding in `app/config/initializers` that was looking for files that didn't exist. This only popped up in the production env.
