Travis CI change history: Builds are not triggering for travis-ci.com

Travis CI’s major outage prevented travis-ci.com Linux and Windows builds from triggering from 2020-09-24 09:12 UTC to 2020-09-24 10:14 UTC (1 h 1 min). The postmortem cited a Bitbucket implementation infinite loop involving suspended users or missing repository permissions, causing VCS instability and high memory usage; the fix checks the suspended flag.
