> * Should handle default value when there is no key in the object
> {noformat}
> var o = Em.Object.create({
> p1: {a: 1, b: 2, c: 3},
> p2: 'd',
> p3: Em.computed.getByKey('p1', 'p2', 100500)
> });
> console.log(o.get('p3')); // 100500 - default value is returned, because
> there is no key `d` in the `p1`
> {noformat}
> * {{App.TestAliases.testAsComputedGetByKey}} should supports checking default
> value and should be able to process provided map instead of traversing throw
> tested object
> * {{App.TestAliases.testAsComputedGetByKey}} should use `to.be.eql` instead
> of `to.be.equal` (`equal` doesn't work for objects, arrays etc)
