Re: ec2-plugin occassional traceback

I've experienced the same issue. It was caused by some of my builds not having a label because they have `agent any` defined in their pipeline.
The PR https://github.com/jenkinsci/ec2-plugin/pull/431 solves this issue by ignoring queued builds without any label.
