Look into coherent PromiseResolver async/await issue

[mizx]

Coherent GT uses an older implementation of Promise which is different than the finalized ES6 one.

This causes problems when using async/await and gives the following error in coherent:
PromiseResolver is not a function (evaluating 'resolve(result.value)')

Including bluebird solves the problem but I'd rather not include bluebird just to get around this.

Coherent's Promise object doesn't initialize until after the react App component mounts to DOM. Had to put in a hack: c95552c

Considering this a non-issue. RXJS fromPromise seems to handle both Chrome and Coherent Promises just fine.

Future version of coherent will have standard version of Promises.
