Make tests pass in github codespaces (#2437)

* Make tests pass in github codespaces

There were a few tests which didn't specify a host or port which wasn't working well inside the codespaces docker environment.  Added host & port where required.  Also noticed one test wasn't actually _testing_, it was just `console.log`-ing its output, so I added proper assertions there.  Finally set `PGTESTNOSSL: true` in the codespaces environment until I can get the postgres docker container configured w/ SSL...which I will do l8r.

* lint
