Nested attributes don't get permitted properly if the association is not the name of the class

[jonaizen]

Doing this:

class TaskType < ActiveRecord::Base
  TaskType  has_one :providers_description_cta, class_name: 'Cta', as: :actionable
end

And:

config.task_type do
  nested :providers_description_cta
end

config.cta do
  scalar :type, :text, :url, :phone
end

Doesn't work because it doesn't realize that :providers_description_cta is a :cta. I should be able to specify what class to use by saying as: :cta
