    [SPARK-26732][CORE][TEST] Wait for listener bus to process events in 
SparkContextInfoSuite.
    
    Otherwise the RDD data may be out of date by the time the test tries to 
check it.
    
    Tested with an artificial delay inserted in AppStatusListener.
    
    Closes #23654 from vanzin/SPARK-26732.
