Fixed attributes_with_attr_encrypted method.
Fixed attributes_with_attr_encrypted method.

- ActiveRecord passes two arguments, not one.
- The attributes_without_attr_encrypted method is not actually sent unless
  .send is explicitly used, because ActiveRecord is passing two
  arguments it's attempting assignment.
- Please see
