stop using display suite layout and just use node template in drupal 8

Basically, this is ugly:

layout–onecol–node-tile.html.twig

compared to:

node–tile.html.twig

and i’m not using any DS features for layout and i’m pretty sure it’s adding extraneous variables weighing things down even more than Drupal already does and i just don’t want to do it and want it gone.

Ugh.
