Controller `action` ignoring fix

In dev now `action` of controller is being ignored: `'run'` is used instead.
```js
Router.map(function () {

    this.route('someRoute', {
        path: '/some-path',
        controller: 'SomeController'
    });

});

SomeController = RouteController.extend({

    template: 'someTemplate'
    
    action: function () {
        console.log('SomeController action executed');
    }

});
```
There is nothing in console after navigating to `/some-path`.
