Description of problem:
When creating new projects (with a customized template which creates a secret and the default serviceAccount), customer gets random errors about the existance of such serviceAccount.


Attached:
 - master-config.yaml and project-template.yaml.
 - oc new-app --loglevel 9 for a valid and a some failed new project
 - master logs containing the previous errors


Version-Release number of selected component (if applicable):
oc version
oc v3.7.23
kubernetes v1.7.6+a08f5eeb62
features: Basic-Auth

Server https://master-internal.dev.ose.keybank.com:8443
openshift v3.7.23
kubernetes v1.7.6+a08f5eeb62


How reproducible:
Randomly


Steps to Reproduce:
1. Install OpenShift
2. Customize project request template with attached template
3. Customize master-config.yaml to not include "default" in the serviceAccountConfig: managedNames: list.
4. Create several new projects


Actual results:
It randomly fails with:
Error from server (InternalError): Internal error occurred: serviceaccounts "default" already exists


Expected results:
No errors.


Additional info:
In the logs there are a few new-project which failed because the project was still being deleted after a previous error. Please omit it. I haven't deleted them of the files to better match the logs in master logs.
