Simplify test execution (#400)

Use the stdlib standard entry point for running tests through the
command:

    python -m unittest discover

Docs: https://docs.python.org/3/library/unittest.html#unittest-test-discovery

This automatically looks for files with the test_ prefix and runs them
as tests. This removes the need for the custom test entry point script,
all_tests.py.
