When using papertrail with mock models papertrail takes the wrong `item_type` about paper_trail HOT 1 OPEN

We are running into a similar situation where we have a weird setup with a shared module that defines logic between two ActiveRecord classes that write to the same database table and are treated as the same entity.

We want to be able to track the history as a single entity, doesn't matter which of the two classes triggered the change. This looks like:

class Shared
  extend ActiveSupport::Concern

  included do
    self.table_name "shared_model"

    has_paper_trail(
      meta: {
        item_type: "SharedModel"
      }
    )
  end
end

class Foo
  include Shared
end

class Bar
  include Shared
end

After the upgrade to PaperTrail 14 this is now also throwing an error. And if we would remove the item_type setting it would result in the versions table having entries for Foo and Bar instead of SharedModel.

If possible we would also like to have an option to configure this somewhere.
