src: yield empty maybes for failed AsyncWrap::MakeCallback calls
Use an empty MaybeLocal<Value>
as the return value for
AsyncWrap::MakeCallback()
if an exception occurred,
regardless of MakeCallback
depth.
Unfortunately, the public API can not make this switch without a breaking change (and possibly some kind of deprecation/renaming).
