Upgrading to v0.4.12 causes error: calling set on destroyed object

[xcskier56]

Upgrading beyond v0.4.12 has started to cause some of my model tests to hang and fail when I create another record in the test. I've tested this in almost all of the version beyond 0.4.12 up to the latest release and it is still happening.

I've created a twiddle that demonstrates the error: https://ember-twiddle.com/70b2098e178cf10b87969ac4b28a5ba3?openFiles=tests.unit.models.user-test.js%2C

Basically, with a user, and relationship model, I create the relationship in the test and test that the two different directions on the relationship are working properly. This is a more simplistic test than my actual one, but the issue is the same.

I'm using Ember 1.13.13, and Ember Data 1.13.15. This is happening with all of my other model tests that use a similar pattern.

I setup the test based on the ember-data test here:

models/user.js

import DS from 'ember-data'

export default DS.Model.extend({
  firstName: DS.attr('string'),
  inboundRelationships: DS.hasMany('relationship', {
    async: true, 
    inverse: 'followed'
  }),
  outboundRelationships: DS.hasMany('relationship', {
    async: true,
    inverse: 'follower'
  })                  
});

models/relationship.js

import DS from 'ember-data'

export default DS.Model.extend({
  confirmed:  DS.attr('boolean'),
  followed: DS.belongsTo('user', {
    async: true,
    inverse: 'inboundRelationships'
  }),
  follower: DS.belongsTo('user', {
    async: true,
    inverse: 'outboundRelationships'
  })                  
});

test:

import { moduleForModel, test } from 'ember-qunit';

moduleForModel('user', {
  // Specify the other units that are required for this test.
  needs: ['model:relationship']
});

test('followers', function(assert) {
  const store = this.store();
  const user = this.subject();

  let relationship, user2;

  Ember.run( function() {
    user2 = store.createRecord('user');
    relationship = store.createRecord('relationship',{
      followed: user,
      follower: user2,
      confirmed: true
    });
  });

  assert.equal(user.get('inboundRelationships.length'), 1)
  assert.equal(user2.get('outboundRelationships.length'), 1)
  // error happens after test.
})

Sorry for letting this linger so long, this issue is quite out of date and likely the underlying problem has been fixed. Initial implementation of the new ember-qunit API (from emberjs/rfcs#232) has landed and will be included in 3.0.0 release soon.

Closing as I do not believe that this issue can be addressed in the current ember-qunit@2 API.
