DS.RecordArray has no reference to Ember.Enumerable#reject

[tricknotes]

I cannot use Ember.Enumerable#reject from DS.RecordArray.
This cause is that DS.RecordArray#reject references Ember.DeferredMixin#reject.

DS.RecordArray has conflict of mixin's method name.

Yup, this will take a while to fix, I think RSVP 2.0 doesn't have reject so once ember switches to it it will be fine. There is a failing test at #861

Seems like this will be fixed by the extraction of Promises that @wycats, @tomdale and @stefanpenner have been pursuing.

This issue was fixed.
