Throw exception on circular reference detection
Out-the-box this isn't common... but into Symfony framework this kind of issue can happen frequently when we're overriding a template from third-party bundle (see main issue https://github.com/symfony/symfony/issues/17557)
```twig
{# app/Resources/AcmeBlogBundle/views/Blog/index.html.twig #}
{% extends '@AcmeBlog/Blog/index.html.twig' %}
{% block title 'New Title' %}
```
This exception avoids inifite loop or maximum execution time for this case, by detecting a recursive loading when a template extends from itself, thinking to override the parent template which has the same namespace + template name.
