These tests will log target verifier did not check any events since there are no events on the target. I added a separate test to check target verifier events below so I will ignore that error here
Same changes for tests below

I wasn't sure how to test this in the ruby integration tests since in integrationferry here we only pass the incorrect tables. perhaps we pass the message as well?

#263
For InlineVerifier:
check if
rowsChecked > 0when we runVerifyDuringCutover.if no rows were checked, return
VerificationResult.DataCorrect = FalseFor TargetVerifier:
check after we run
StopTargetVerifierto see if we verified any eventsif no events were checked, we log and return an error, copydb and sharding will then panic
