fix: *_rfc6570 to support Hash argument

[arkirchner]

When a Rails Engines *_rfc6570 method is called from the main app, the argument will be a hash. *_rfc6570 needs to support both keyword arguments and a hash argument.

Sorry for not getting back to you about this in the last PR. Only now I realized that this issue is present when calling the template from a Rails engine from the main app.

We are moving services into engines to fold them into the main app. We are using Draper decorators that have an application controller passed in from the main app. Engine decorators call URLs through the main app's routes.

module SomeEngine
  class ApplicationDecorator < Draper::Decorator
    # Draper will use the main apps helper by default.
    def h
      super.some_engine
    end
  end
end
