Simplify test setup and remove test runner script

The tests can be run with `python -m unittest discover` instead.  When
run with python3 they show some deprecation warnings that where not
shown before but they do not fail.

Additionally this reduces the missed lines count in the test coverage
report to 0 for nearly all test files.
