[SPARK-16251][SPARK-20200][Core][Test]Flaky test:
org.apache.spark.rdd.LocalCheckpointSuite.missing checkpoint block fails with
informative message
## What changes were proposed in this pull request?
Currently we don't wait to confirm the removal of the block from the
slave's BlockManager, if the removal takes too much time, we will fail the
assertion in this test case.
The failure can be easily reproduced if we sleep for a while before we
remove the block in BlockManagerSlaveEndpoint.receiveAndReply().
## How was this patch tested?
