Restore tests (updated) (faust-streaming#141)

* Restore testing

A lot of test classes are named test_*, which makes pytest *not* find them by default

* Fix failing unit test after fix for faust-streaming#42

* Restore tests by adding timeout arg

* Restore original behaviour of _wait, don't always wait for signal_recovery_start

* Restore a few of the aiokafka tests

* Restore a few app tests

* Run event path verification in aiokafka driver

* lower minimum code coverage to 59%

* reformat examples/livecheck.py with black

* rename test class to match Test naming pattern

* fix test__resume_streams, as assignment() returns a set
