Title: Should use last build workspace, not just "some" workspace.

According to javadoc http://javadoc.jenkins-ci.org/hudson/model/AbstractProject.html#getSomeWorkspace%28%29 getSomeWorkspace returns "a workspace for some build of this project", but we actually need the workspace of the last build. That matters, when you have several nodes where the job has run.
