App crash due to unhandled promise rejection in Gus.getWorkItemIdByName

[mpsenn]

This TypeError is unhandled, causes a promise to reject, and crashes the app. This function looks like it doesn't really understand Promises either, since it mixes callback functions and async/await.

Wishlist:

1. Fix the app crash.
2. Refactor this class to correctly use Promises.
3. Install a global unhandledpromiserejection logger? Not sure if we want these to lead to app crashes, or just error logs.
