Unexpected behavior with functions in concatenated properties

[mbixby]

Fiddle

A = Ember.Object.extend({ concatenatedProperties: ['shared'], shared: [] })
B = A.extend({ shared: Ember.K })

console.log( B.create().get('shared') ) 
//=> `Ember.K` (expected `[Ember.K]`)

console.log( B.create({ shared: Ember.K }).get('shared') ) 
//=> `[Ember.K, Ember.K]` as expected

@mbixby This does seem unexpected. Can you create a failing test for https://github.com/emberjs/ember.js/blob/master/packages/ember-metal/tests/mixin/concatenatedProperties_test.js ?

I'll have some time to fix it tomorrow.
