Simplifying test to use JenkinsRule.assertLogContains.
f43a450c31d3875e72defa8400c6ada43bfc3ad0 addendum: during migration, if nothing else is being fingerprinted besides archived artifacts, then there is no reason to keep the separate fingerprint publisher at all.
[FIXED JENKINS-23027] Added Launcher.ProcStarter.quiet option.
