Update CI to node v16 (cruise-automation#715)

## Summary

The previous PR only bumped the version, but didn't change the CI config. This is now getting fixed along with the errors discovered in CI:
 - Starting npm cli v7, the user for npm run scripts changed (now this is owner of current directory: https://docs.npmjs.com/cli/v8/using-npm/scripts#user) so we need to update CircleCI script accordingly
 -  `unhandledRejection` was upgraded from Warning to Error, so we need to disable this check
 - Error messages for undefined attributes got changed
 - Couple of libraries updates



## Test plan

- Green CI. 
- Screenshots test shows  very minor differences (pixel level) so should be fine.
