Step 4 - Tutorial code different than github code

Remove : **~~inject~~**(function(**~~$controller~~**)
In Github test/unit/controllersSpecs.js :

```
it('should create "phones" model with 3 phones', inject(function($controller) {
  expect(scope.phones.length).toBe(3);
}));
```

in official tuto : 

```
it('should create "phones" model with 3 phones', function() {
  expect(scope.phones.length).toBe(3);
});
```
