The NOTICE log level (25) is added to logging when utils.monkey_patch
is executed. Depending on test execution order, this may not have
happened when some unit tests run, so LogRecords at NOTICE level may
have the default level name of 'Level 25'. FakeLogger doesn't have a
key in its lines dict for 'Level 25', so those tests would blow up.
