ValueError when running Keystone tests

[Lance Bragstad]

When running the Keystone tests against the latest master branch I get the following error:

${PYTHON:-python} -m subunit.run discover -t ./ ./keystone/tests --load-list /tmp/user/1000/tmpAaHUxr
No handlers could be found for logger "keystone.catalog.core"

ValueError: need more than 0 values to unpack

The tests do succeed but the value error is reported during the test run. Latest commit is:

    Cleanup eventlet use in tests

    The tests in test_wsgi should stop the server once the test is over,
    otherwise it would continue running and potentially affect other
    tests.

    Also, there were a couple of tests that did
    environment.use_eventlet() in setUp, which has no effect since this
    was already done in keystone.tests.core, and it's incorrect to put
    this in a test setUp since it would affect other tests as it's an
    application-wide library setting.
