Let we have a job that points to GitLab repository. Any Jenkins changes view with a list of commits provides a wrong link to GitLab commit (changeset).

Example page: https://JENKINS_URL/job/JOB_NAME/job/master/1/changes

Expected link: https://gitlab.com/OWNER/REPO/commit/HASH

Actual link: https://gitlab.com/commit/HASH

I suppose the `GitLab::getChangeSetLink` is broken since maybe gitlab 7. It should include repository information in the URL.
