test: fix skips (#95)

The ephemeral port and host skips are no longer valid, so tests have been added for those.
The other skipped test is now covered by the interface tests, so it's no longer needed.

* chore: add node 12 to ci
* chore: add docs and dist to gitignore
* chore: clean up travis file
