Commit e0f373ee4 fixed up races in Cluster::connect_fails when using log_like. t/002_client.pl didn't get the memo, though, because it doesn't use Test::Cluster to perform its custom hook tests. (This is probably not an issue at the moment, since the log check is only done after authentication success and not failure, but there's no reason to wait for someone to hit it.) Introduce the fix, based on debug2 logging, to its use of log_check() as well, and move the logic into the test() helper so that any additions don't need to continually duplicate it.
