testComplianceEnable supports variable number of audit messages (#1920)…

… (#1924)

We were seeing test failures where on higher end computers there would
be duplicate audit messages for the index mapping creation.  Then when
run inside GitHub Actions there would only be 2 messages.  This doesn't
look like an overt product issue, overlogging of requests, but the test
case was not handling it well. Also improved the failure message response
for faster future debugging.
