[SPARK-19565] Improve DAGScheduler tests.
## What changes were proposed in this pull request?
This is related to #16620.
When fetch failed, stage will be resubmitted. There can be running tasks
from both old and new stage attempts. This pr added a test to check the case
that success of tasks from old stage attempt should be taken as valid and
partitionId should be removed from stage's pendingPartitions accordingly. When
pending partitions is empty, downstream stage can be scheduled, even though
there's still running tasks in the active(new) stage attempt.
