Trevor Norris bb1bd76395 async_wrap: call callback in destructor
Call a user's callback to notify that the handle has been destroyed.
Only pass the id of the AsyncWrap instance since the object no longer
exists.

The object that's being destructed should never be inspected within the
callback or any time afterward.

This commit make a breaking change. The init callback will now be passed
arguments in the order of provider, id, parent.
