ActionController subscriptions overwritten.

[tristandunn]

In 0.9.0 ActionController::SerializationAssertions defines setup_subscriptions and teardown_subscriptions methods, but doesn't call super. Which means the ActionController::TemplateAssertions subscriptions are never created, which is breaking the assert_template assertion.

I'm not sure if calling super is the best fix. I'm up for creating a patch once I know the preferred solution.

Does renaming setup_subscriptions and teardown_subscription help?

Yes. That's probably a better solution than super.

@bolshakov My bad, totally didn't see your pull request until I was opening mine. Not much different, but I added a test for it.
