As initially written the test does not work other than in a CI environment because it relies on an empty tag history. Rewrite so we can guarantee that, by creating a new image. Also add slightly more helpful tests: the initial tests would just show "expected 0, got 1" which is unhelpful. Tweak so we test on actual history contents, which will show more informative messages on failure. And, finally, clean up after ourselves. Signed-off-by: Ed Santiago <santiago@redhat.com>
