## Bug Description
I setup a custom preference center landing page. It is published with a template in code mode and is in language fr. I send an email where I have assigned this preference center landing page to it. The email is in language fr and is using the template blank. When I click on the unsubscribe link. I see the template of my landing page encapsulated in the `message.html.twig` extends the `base.html.twig` templates of the blank template. Moreover, a custom body and html header tags are added to the template.
The generated HTML :
```html
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" type="text/css" />
<script data-source="mautic">
...
</script>
</head>
<body>
<div>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html>
<body>
my preference center landing page code mode content
</body>
</html>
</body>
</html>
```
I should be able to have a custom template for my custom landing page which is not linked to the template of the email I access the page from and without any modification done by mautic.

### Steps to reproduce
1. Setup a custom preference center page with template in code mode
2. Send an email with template blank and the previous preference center page assigned to this email
3. Click on the unsubscribe link in the email
### Log errors
No errors
I have tracked it here :
In [PublicControllerL242](https://github.com/mautic/mautic/blob/37ed5ee87900522c888b09ed3857ad0452fb33df/app/bundles/EmailBundle/Controller/PublicController.php#L242) :
```php
$event = new PageDisplayEvent($html, $prefCenter, $params);
$this->get('event_dispatcher')->dispatch(PageEvents::PAGE_ON_DISPLAY, $event);
$html = $event->getContent();
```
Listeners on this event are modifying the custom code of the preference center landing page. This is not the most troublesome part. It could stay as it is. However, the fact that it reuses the email template when we are in `mautic as code` template mode for the preference center is troublesome :
```php
// here $template is the one from the email from which we clicked on the unsubscribe link.
$contentTemplate = $this->factory->getHelper('theme')->checkForTwigTemplate(':'.$template.':message.html.php');
///...
$viewParams = [
'email' => $email,
'lead' => $lead,
'template' => $template,
'message' => $message,
];
return $this->render($contentTemplate, $viewParams);
```
I can propose a PR if you point me in the correct direction you would like this behavior to be changed/fixed. Maybe something like if custom preference center page is enabled and is a `mautic_as_code` template, override `$contentTemplate` to use a dedicated `empty.html.twig` template which just print `{{ message|raw }}`.
