web-platform-tests: uncaught exceptions around `promise_tests`

TaskCluster was configured to log information about tests which use promise_test and produce uncaught exceptions in Chrome or Firefox. The commit that implemented that logging is:

https://github.com/bocoup/wpt/commit/38972d9d995a652dbe4cbe13320bc7a9b6d4c617

The raw data was downloaded with the following command:

./wpt tc-download --artifact-name suspicious.txt --repo-name bocoup/wpt --ref promise-uncaught --out-dir tc-logs/promise-uncaught
