job fails if job type is anything other than "GitHub organization"

Example output:

11:22:36 + ORG_REPO_BRANCH_ARRAY=(${JOB_NAME//// })
11:22:36 + ORG=some_repository_name
11:22:36 + REPO=some_branch_name
11:22:36 + TOKEN_PARAM=access_token=****
...
11:22:36 + echo '{' '"message":' '"Not' 'Found",' '"documentation_url":' '"https://developer.github.com/enterprise/2.8/v3"' '}'
11:22:36 + python -c 'import sys, json
11:22:36 
11:22:36 content = json.load(sys.stdin)
11:22:36 for status in content["statuses"]:
11:22:36     if status["context"] == "code-coverage":
11:22:36         print status["description"].split("%")[0]
11:22:36         sys.exit(0)'
11:22:36 Traceback (most recent call last):
11:22:36   File "<string>", line 4, in <module>
11:22:36 KeyError: 'statuses'

Root cause is parsing of $JOB_NAME into $ORG and $REPO, since $ORG is not present for non-org job types.

Should get the org from somewhere else or at the very minimum not fail the build.
