Title: Fix for bug resulting from top-level class redefinition

I was seeing a bug that resulted from my `User` class being skipped for not inheriting from `ActiveRecord::Base`:

```
Skipping non-ActiveRecord model User...
```

However, `User` does in fact inherit from `ActiveRecord::Base`. I tracked it down to User being redefined as a module during class loading. I added some logic to avoid such redefinition.
