Ember.computed.sort doesn't update when live RecordArray updates.

[bravo585]

I just upgraded from Ember 1.13 to Ember 2.1. I noticed Ember.computed.sort no longer updates if a live RecordArray updates.

For example, if I have:

users: Ember.computed(function() {
  return this.store.filter('user', {filter: {'is-active': true}}, function(record) {
    return record.get('isActive');
  })
}),

sortLastName: ['lastName:asc', 'firstName:asc'],
usersSorted: Ember.computed.sort('users', 'sortLastName'),

And I print out:

{{#each usersSorted as |user|}}
  {{user.lastName}}, {{user.firstName}}
{{/each}}

If I add a new user, the users list will update, but the usersSorted list will not.

I think this is the same as #12475

@bravo585 would you be able to create an example using jsbin, jsfiddle, or ember-twiddle? Perhaps instead of store.filter return a promise with the content as a RecordArray

Actually this might be related to #12212 since it happened after upgrading to 2.x. Is your Ember.computed.sort in a component or other control that has multiple active instances at the same time?

If it is related to #12212 ... you could try using my addon ember-computed-sortby.
