davidot 244adb371f LibJS: Spin the event loop until await has completed ...

Before this the event loop was spun until the state of the promise was
not pending, however it is possible that a promise has already been
fulfilled/rejected when awaiting it. This could then lead to a crash
below as it would not pump the event loop in such cases.
Although this change is in LibJS, it really only impacts any usage of
LibJS within a EventLoop environment such as LibWeb.

Instead of checking the state of the promise we know check that success
has a value which can only happen if either the fulfilled or rejected
closure set up by await are called.
