damos_quota_goal.py selftest see if DAMOS quota goals tuning feature increases or reduces the effective size quota for given score as expected. The tuning feature sets the minimum quota size as one byte, so if the effective size quota is already one, we cannot expect it further be reduced. However the test is not aware of the edge case, and fails since it shown no expected change of the effective quota. Handle the case by updating the failure logic for no change to see if it was the case, and simply skips to next test input.
