The Cobertura "Coverage Report" link on a job links to $jobname/cobertura which
forwards to $jobname/lastStableBuild/cobertura when it should actually go to
$jobname/lastSuccessfulBuild/cobertura.

Reasoning: Clicking the Coverage Report link on a job will only show coverage
info for the last build that was completely stable, even though later builds
might have changed the coverage drastically. By changing the link to
lastSuccessfulBuild the latest info is available from the job page.

Even worse, on jobs which have not yet been stable (not that I have any of
those), it results in a not-so-pretty 404 error
