Work around a bug in the Jenkins queue API.

https://issues.jenkins-ci.org/browse/JENKINS-27256

1.601 broke the ability to get a build's URL before the build had
actually started. The bug is pseudo-fixed, but would require
installing a new plugin and fixing the python jenkinsapi plugin for
the time being to use /queuefix/ rather than /queue/.

Just avoiding logging a URL for now.
