Allow running cms-bot job with code being tested

[iarspider]

Currently, cms-bot job uses master branch if triggered by GitHub webhook. This makes testing changes to process_pr (e.g. #2418) hard, since one needs to trigger the job manually to run the tests and to get the results.

Since process_pr has access to sensitive information (GH token), the tests should only trigger if the PR author is from core (or some other special) team.
