(MODULES-1156, MODULES-769) Remove unnecessary anchors

`apt::ppa` and `apt::setting` don't actually include `apt::update` so
anchors are unnecessary. Move `apt` to use contain instead of anchors,
since it wasn't anchoring properly anyways. Update the tests to make
sure it can have settings and ppas depending on each other without
cycles.
