[SC-9624][SS][TESTS] Don't access `lastExecution.executedPlan` in StreamTest
## What changes were proposed in this pull request?
`lastExecution.executedPlan` is lazy val so accessing it in StreamTest may
need to acquire the lock of `lastExecution`. It may be waiting forever when the
streaming thread is holding it and running a continuous Spark job.
This PR changes to check if `s.lastExecution` is null to avoid accessing
`lastExecution.executedPlan`.
## How was this patch tested?
Jenkins
