Fix controller not being included

@MarcoDeBortoli @alistairstead this fixes multiple attempts to create the controller. MageSpec still asks for the Request and Response to be passed to the controller as in:

```php
<?php

namespace spec;

use PhpSpec\ObjectBehavior;
use Prophecy\Argument;

use Zend_Controller_Request_Abstract as Request;
use Zend_Controller_Response_Abstract as Response;

class Training_First_IndexControllerSpec extends ObjectBehavior
{
    function let(Request $request, Response $response)
    {
        $this->beConstructedWith($request, $response);
    }

}
```

Should we be generating a spec that extends `ControllerBehavior` instead of `ObjectBehavior`?
