docs(ngController): do not attach a controller twice

Browse source 
A common mistake for beginners is to attach a controller in both the
$routeProvider and also in the html document using the ng-controller
directive. This change highlights this, to help prevent developers from
doing so in the future.

Closes #4409

* * Controller — The `ngController` directive specifies a Controller class; the class contains business
* logic behind the application to decorate the scope with functions and values
*
* Note that an alternative way to define controllers is via the {@link ngRoute.$route $route} service.
* Note that you can also attach controllers to the DOM by declaring it in a route definition
* via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
* again using `ng-controller` in the template itself. This will cause the controller to be attached
* and executed twice.
