Title: Use === to know whether the object is Array or not

Using `#is_a?` could be a problem if the object doesn't have such a method. The issue often happens when we use a class that inherits `BasicObject` like [Jbuilder](https://github.com/rails/jbuilder).

This patch fixes the issue and ActiveDecorator does work with Jbuilder now.
