CtsVerifier case "Condition Provider test" failed

During "Condition Provider test" , it always stay at step "Unsubscribe to AUtomatic zen rule"
Because after call removeAutomaticZenRule , onUnsubscribe is called slower ,
conditionId didnt remove from mSubscriptions in time , so it cause case failed.
Also , retest wont do setup before test , only call test() function ,
so that the rule wont recreate as normal
