The apply_scopes_if_necessary method will in some instances return the model itself - it seems in the latest versions of rails you can't call .each on the model without first creating a scope.
Solution would be to just call all, however in older versions of Rails this will return an array, which isn't expected. where(nil) might be more backwards compatible for now.
