Break out of teardown in test_replica_promotion.py if no config
These tests are all skipped if there is no YAML configuration
file passed but the teardown method is always called and since
there is a reference to the Config object this blows up if just
ipa-run-tests is executed.
Look at the config and break out if no domains are set.
