promiseCapability.[[Resolve]] is not a function

[trueter]

Hey Folks

I started getting this weird error in Google Chrome Canary yesterday.
Uncaught (in promise) TypeError: promiseCapability.[[Resolve]] is not a function | undefined:1

On the chromium issue tracker it has been stated that it is important for subclassed Promises to act similarly to new the Promise ES2015 constructor as defined in the ECMA-262 draft from December 20th.

I don't know if this is to be considered an issue with Bluebird, but coudn't rule it out either.

Thanks for looking into this.

Looks like the issue is related to core-js, not bluebird: zloirock/core-js#159.
