Duplicate "Request for testing" comments.

I have jenkins set up to run multiple jobs for a single project, but this causes ghprb to post a comment per job in PRs made by non-whitelisted people. Is there a way around this?

Also interested in a solution to this. I cleverly tried to include $JOB_NAME in the notice, so it was at least more obvious why it was commenting multiple times, but that worked about as well as expected.

I sent a PR for this a year ago, but haven't had a chance to rebase it against current master for a long time. janinko#276
