- When lazy load hooks were triggered we were using
  `Object.instance_eval` which evaluates the block in the context of
  the class being passed. Most of the time that class was a
  `Class`. If one wants to define a instance method on the class then
  it wasn't possible.

  ```ruby
    class A; end;
    A.instance_eval do
      def foo
        puts 'bar'
      end
    end
    A.new.foo #> NoMethodError: undefined method `foo`
    A.foo #> bar
  ```
- This PR checks what object is passed when triggering the hooks and
  either call `class_eval` or `instance_eval`. My rational and assumptions being
  that if an instance of a class is passed, then the blocks needs to
  evaluate in the context of that instance (i.e. defining a method
  should only define it on that instance).
  On the other hand, if a Class or Module is passed when triggering
  hooks, then defining a method should define it on the class itself
