ci: run pure install tests

GitHub actions clone the repo for test files, install current branch
module with pip and run unittest (same as ran under setup.py) tests.

"Run tests" stage is full of ResourceWarning messages. It's not clear
why these messages are suppressed by `setup.py test`. We also can't
disable these warning separately from application warnings (some tests
rely on application warnings).
