This change should fix the bug in GoogleContainerTools#294, where kaniko wasn't recognizing that a stage would be used in a later build and so wasn't saving it as a tarball. Each stage of the Dockerfile has a Name and a BaseName (FROM BaseName as Name), but if a Name isn't specified then it's set to the same value as BaseName. Our test cases weren't complete enough to catch this distinction, which is why this bug occurred. I added more test cases to the unit tests to make sure this fix works.
