[SPARK-23962][SQL][TEST] Fix race in currentExecutionIds(). SQLMetricsTestUtils.currentExecutionIds() was racing with the listener bus, which lead to some flaky tests. Wait till the listener bus is empty. I tested by adding some Thread.sleep()s in SQLAppStatusListener, which reproduced the exceptions I saw on Jenkins. With this change, they went away.
