Message:

Add two logging-related test helpers: a function to retrieve all
registered logger names and another one that removes loggers from
global (Python) registry, if they are not contained in the list. In
tests you can use the former to determine the set of pre-test loggers
and the latter to remove all loggers added during tests.
