Always uses User Feed when using Model Binding

[r0bdiabl0]

The following lines of code do not allow you to use different actors aside from users using the user_feed as the following function is hard coded to use the user feed:

$this->userFeed = $this->config->get("stream-laravel::user_feed");
....
$feed = $this->getFeed($this->userFeed, $instance->activityActorId());

It should change based on if you set the following in the model:

public function activityActorMethodName()
    {
        return 'group';
    }

The code should read like this instead:

$feed = $this->getFeed($instance->activityActorMethodName(), $instance->activityActorId());
