I see some usual suspects on test failures, but
`org.apache.kafka.connect.integration.SourceConnectorsIntegrationTest.testSwitchingToTopicCreationEnabled`is
new. Looking at the stack trace, doesn't seem relevant to the changes made in
this PR.

Is there some relation I'm missing, or should I create a new issue for this
flaky test?
