      Bug:

      When you delete a branch and create it again within seconds (2 seconds) on your remote Bitbucket server, jenkins is not done processing the remove event when the create event comes, preventing it from starting a new job.

      Steps to reproduce:
      create a branch called eg. test/sal and let it run until finish.

      After that, redo the last commit, and delete the remote branch and push again

       git commit -a --amend -C HEAD && date && git push origin :test/sal ; sleep 2 && git push origin test/sal && date

      result:
      Sometimes (every second time, but varying) the trigger is not executed.

      Bad run logs:

      Notice the timestamps for "Received/Finished".
      In the bad example, REMOVED event processing does not finish until after the CREATED event is started and finished. In the good example, the REMOVED event does finish after CREATED starts, but before it finishes. This does indeed allow for a scenario where the processing of the CREATED event races with the REMOVED event.
