Merge pull request #1217 from dimaqq/ci-bring-unit-tests-back-to-life

#1217

A few changes interplayed badly and we were running `tox -e py3` in github actions, which only installed the dependencies and didn't run the unit tests 😱 

This PR:
- run unit tests again
- run integration tests against Juju 3.6
