      When using Mongoid 8, a FrozenError is raised if a relation is created with embeds_one autobuild: true and the model is subsequently deleted.

      Steps to Reproduce

      Here is the code snippet to reproduce the issue:

      require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'

  gem 'mongoid', '~> 8.0.8'
  # gem 'mongoid', '~> 7.5.4'
end

Mongoid.configure do |config|
  config.clients.default = {
    hosts: ['172.18.0.4:27017'],
    database: 'mongoid_test',
  }
end
Mongoid.purge!

class Article
  include Mongoid::Document

  embeds_one :intro, autobuild: true # No error with `embeds_one :intro` only
end

class Intro
  include Mongoid::Document

  embedded_in :article
end

article = Article.create!
article.destroy
pp article.intro # It should be nil but raise a Frozen Error

       

      Here is the backtrace of the error:
