Creating subclass does not create superclass object until superclass object is needed

[lowjoel]

the definition of the acts_as association does not implicitly build the superclass object, only accessing it through #actable would.

I propose implementing another method with the same name as the association which calls super or builds the superclass object, then aliasing actable to that method instead.

If this is okay with you, I'd quickly write a PR

That sounds good, thanks
