[SPARK-17318][Tests]Fix ReplSuite replicating blocks of object with class
defined in repl again
## What changes were proposed in this pull request?
After digging into the logs, I noticed the failure is because in this test,
it starts a local cluster with 2 executors. However, when SparkContext is
created, executors may be still not up. When one of the executor is not up
during running the job, the blocks won't be replicated.
This PR just adds a wait loop before running the job to fix the flaky test.
## How was this patch tested?
Jenkins
