this.subject calls not generating new instances

[Asgaroth]

Not sure if the title of the issue is correct, but it seems that calling this.subject is not instantiating a new object.

// component definition
export default Ember.Component.extend({
  attr: null,

  init: function() {
    this._super();
    console.log(this);
  }
});


// tests
moduleForComponent('some-comp', {
  // specify the other units that are required for this test
  // needs: ['component:foo', 'helper:bar']
  beforeEach: function() {
    var componentA = this.subject({attr: 'foo'});
    var componentB = this.subject({attr: 'bar'});
  }
});

Expected in the console:

Class {attr: "foo", _outlets: Object, elementId: "ember205", _state: "preRender", currentState: Object…}
Class {attr: "bar", _outlets: Object, elementId: "ember205", _state: "preRender", currentState: Object…}

Instead got:

Class {attr: "foo", _outlets: Object, elementId: "ember205", _state: "preRender", currentState: Object…}

Note: also happens in a regular test so its not a beforeEach issue

Please let me know if I am just doing something wrong

Subject (and the other helpers) are memoized, and will be ran once then the result is cached. This is intentional...
