Notice error with advanced seo and featured articles

If you activate the sef_advanced_link option (with a plugin or by temporary hardcode it in the router itself, see line 208) you get a notice error by following this steps:

1. Use an empty Joomla! installation for the best test environment (so other menu links will not "fix" the bug)
2. Create a com_content article
3. Set the article as "featured"
4. Go to the default frontpage home link
5. Click on the article
6. Notice: Undefined index: id in components\com_content\router.php on line 278
7. Apply pull request
8. Check again

Why do you get this notice error?
Because featured blog links have no "id" as request parameter.
