500 error with CarrierWave multiple file uploader

Hello, I really appreciate your development of great gem!

I have an issue occurring with CarrierWave multiple file uploader column (named as Topic#images )

I'm getting something very similar. It does not seem to be related with CarrierWave but it did start breaking after changing has_one_attached by has_many_attached with ActiveSupport

I have the same problem.
While I refer to the carrierwave document, I added "images:json" column to Shop model.

And I setted up like this

class Shop < ApplicationRecord
  mount_uploader :images, ImageUploader
  attr_accessor :delete_images
  after_validation do
    uploaders = images.delete_if do |uploader|
      if Array(delete_images).include?(uploader.file.identifier)
        uploader.remove!
        true
      end
    end
    write_attribute(:images, uploaders.map { |uploader| uploader.file.identifier })
  end

  def images=(files)
    appended = files.map do |file|
      uploader = _mounter(:images).blank_uploader
      uploader.cache! file
      uploader
    end
    super(images + appended)
  end
end

After that, when I try to create a new Shop instance with rails_admin view, the following error is displayed.

It seems that "identifier" method can not be used in CarrierWave::Storage::Fog::File

It should be changed "identifier" to "filename" method. This can return the same value we want.
