Fix runtime errors with upgrade to whs@2.0.0-beta.9.1, add yarn lockfile

The `package.json` was fetching `2.0.0-beta.9.1` since it was the
latest in terms of a semver match.

Fixes breaking changes from `2.0.0-beta.8` that were keeping the
starter pack from running "out of the box".

Adds `yarn.lock` to prevent future dependency issues.
