ci: Run tests using PostgreSQL database and mock (#49)

* ci: Run tests using PostgreSQL database and mock

This allows us to use the mock database for quick iterative testing,
and have confidence from CI using a real PostgreSQL database.

PostgreSQL tests are only ran on Linux. They are *really* slow on MacOS
and Windows runners, and don't provide much additional confidence.

* Only run PostgreSQL tests once for speed

* Fix race condition of log after close

Not all resources were cleaned up immediately after a peer connection was
closed. DataChannels could have a goroutine exit after Close() prior to this.

* Fix comment
