TestSplitTransactionOnCluster.testMasterRestartAtRegionSplitPendingCatalogJanitor is flakey

RITs will lead to CatalogJanitor not running, and then parent region will not be cleaned.

As a result, the last assertion of checking if parent region is null will fail.

Error Message

expected:<null> but was:<maven-jdk8-551kz,45127,1563877982046>

Stacktrace

java.lang.AssertionError: expected:<null> but was:<maven-jdk8-551kz,45127,1563877982046> at org.apache.hadoop.hbase.regionserver.TestSplitTransactionOnCluster.testMasterRestartAtRegionSplitPendingCatalogJanitor(TestSplitTransactionOnCluster.java:577)

Currently, the case is only waiting for master be active while not care about RITs completion when master starts up.

Failed test results is attached. We can see CatalogJanitor chore run failed log in it,
