AppEngineRule throws an exception during teardown if an empty datastore-indexes-auto.xml is created during testing. This scenario should be fine, just like if this file has not been created at all. This issue causes some flakiness in tests. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=231229692
