VersionTestCase.test_admin_version_v3 (keystone/tests/unit/test_versions.py) in fact tests public app:

def test_admin_version_v3(self):
    client = tests.TestClient(self.public_app)

It makes sense only in case of V3 eventless setup where public app handles bot endpoints, but I believe it should be tested by a separate test like .test_admin_version_v3_eventlets which will be introduced as part of fix of bug #1381961. Also this behavior was introduced when 2 apps setup was used for eventless.
