Review Request #9721 — Created March 3, 2018 and submitted
If URLAvatarService is disabled, both the TravisCI and CircleCI integrations will fail to create their service user. This is due to attempting to access the URLAvatarService without checking if it is enabled. Here the fix is to check if it's enabled, then proceed with using the service.
Ran the unit tests for both travisci and circleci integrations, as
well as manual testing with my jenkinsci code.
