Bug 1411336

Description of problem:
In running the base pipeline example, I set it up to run periodically (every 30 minutes). Over the last 6 hours it hasn't been able to successfully start a new pipeline build.

Version-Release number of selected component (if applicable):
OpenShift Master:
v3.4.0.38 (online version 3.4.0.11)
Kubernetes Master:
v1.4.0+776c994
Jenkins ver. 2.19.3
Jenkins plugins-
  OpenShift Pipeline Jenkins Plugin: 1.0.37
  OpenShift Sync: 0.1.5

How reproducible:
Deploy sample pipeline and repeatedly run the pipeline, observe failures.


Steps to Reproduce:
1. Login to dev-preview-int
2. Create project
3. Deploy simple sample 
    oc new-app -f https://raw.githubusercontent.com/openshift/origin/master/examples/jenkins/pipeline/samplepipeline.yaml
4. Go to Jenkins console and setup periodic builds

Actual results:
Pipelines eventually stuck in "New" state in OpenShift and no corresponding build jobs in Jenkins, with many log entries in Jenkins like:

SEVERE: Failed to update job
java.lang.IllegalArgumentException: Jenkins already contains an item 'sspeiche-pipeline-sample-pipeline'


Expected results:
My pipeline builds successfully
