Ensure Railtie has eager_load_paths
Ensure Railtie has eager_load_paths

It is possible that gems may define a Railtie without defining
`eager_load_paths` (such as `dotenv-rails`), which causes this function
to fail. Extend the `next` clause to ensure the existence of
`eager_load_paths` to prevent this failure.
