async_hooks: remove promise object from resource
While it doesn't make any difference now. In the future PromiseHooks
could be refactored to provide an asyncId instead of the promise object.
That would make escape analysis on promises possible.
Escape analysis on promises could lead to a more efficient destroy hook,
if provide by PromiseHooks as well. But at the very least would allow
the destroy hook to be emitted earlier. The destroy hook not being
emitted on promises frequent enough is a known and reported issue.
See https://github.com/nodejs/node/issues/14446 and
https://github.com/Jeff-Lewis/cls-hooked/issues/11.
While all this is speculation for now, it all depends on the promise
object not being a part of the PromiseWrap resource object.
