Review comment:
Thanks @cadonna ; I agree. This test should just be verifying that we
first converge on 7, and then that we converge on 8.

Review comment:

a blank on why we need to verify this log line. It seems like _just_ checking
the version number logs and nothing else would be the key to a long and happy
life.
