Run test suite against both engines (#10373)
* Run test suite against both engines

* make eslint happy

* only run `stable` tests on Node 12

* use normal expectation instead of snapshot file

When we run the tests only against `stable` (for node 12), then the
snapshots exists for the `Oxide` build. They are marked as `obsolete`
and will cause the `npm run test` script to fail. Sadly.

Inlined them for now, but ideally we make those tests more blackbox-y so
that we test that we get source maps and that we can map the sourcemap
back to the input files (without looking at the actual annotations).

* properly indent inline css
