Fix conflict with ActiveSupport dependency loading

`Object#require` in ActiveSupport attempts to call their own `load_dependency` method [1], which is overridden in the Adapter class and causes an error when Lotus Model is used with Rails. This addresses the conflict by choosing a different method name.
