Fix org.apache.cassandra.distributed.test.FqlReplayDDLExclusionTest.test

It failed a few times in Jenkins lately. Example:

https://jenkins-cm4.apache.org/job/Cassandra-4.0.0/12/testReport/junit/org.apache.cassandra.distributed.test/FqlReplayDDLExclusionTest/test/

Error Message
Expected: [[1]] Actual: []

Stacktrace
junit.framework.AssertionFailedError: Expected: [[1]] Actual: [] at org.apache.cassandra.distributed.shared.AssertUtils.assertRows(AssertUtils.java:58) at org.apache.cassandra.distributed.test.FqlReplayDDLExclusionTest.test(FqlReplayDDLExclusionTest.java:102)

I was also able to reproduce it locally on the latest 4.0.0 so I believe it is worth it to be checked. 

//CC stefan.miklosovic and bereng as I see you two are the only people who worked on that test up to now so If you have any thoughts to share, as usual, that will be highly appreciated
