Fixing wrong paths - thanks to tip from Daniel Harper in the comments

I didn't intend to put the assets into layout.html.twig (in the bundle), I had
intended for them to live in base.html.twig (in app), which is what we do in
the video. This avoids the problem with adding the bundles config for assetic
in config.yml

After changing it so that Symfony renders the buttons (worked better with generated CRUD code),
this makes the styling *slightly* better, since we lost our .button class
