Let JedisSentinelPoolTest recognizes "aborted failover" and fail fast

* let unit test fail if -failover-abort-* message is produced while waiting to failover
** waiting more is meaningless, and there is nothing we can do
** we can request "sentinel failover" to failover again, but it may can fail again
