Disabled MultiViews in .htaccess

The `MultiViews` option enables Apache to negotiate and serve existing files depending on the request Accept header. For example `/config/test` will resolve to `/config.php/test` when accepting `text/html`.

So it prevents from using route paths beginning with the name of a file present in the `/web` folder. Moreover, this option is not needed because all requests that don't match an existing file are meant to pass through the Symfony front controller.

So this PR removes this option from the `.htaccess`. Note that it is enabled in the default Apache configuration on Ubuntu.

This issue was also a topic here symfony/symfony-docs#3674
