Remove AcmeDemoBundle references

After symfony/symfony-standard#819 and symfony/symfony-standard#818 last year the AcmeDemoBundle doesn't exist so having an article dedicated to it doesn't appear to make much sense. This adapts the article to be focused on removing 'a bundle'.

-    This doesn't apply to the AcmeDemoBundle - no other bundles depend

 Some bundles rely on other bundles, if you remove one of the two, the other
 will probably not work. Be sure that no other bundles, third party or self-made,
 rely on the bundle you are about to remove.
