Crash on deleting ThreadSafeFunction

[legendecas]

static Value Test(const CallbackInfo& info) {
  Object resource = info[0].As<Object>();
  Function cb = info[1].As<Function>();
  ThreadSafeFunction tsfn = ThreadSafeFunction::New(info.Env(), cb, resource, "Test", 1, 1);
  tsfn.Release();
  return info.Env().Undefined();
}

The case would have a great chance to crash with SIGABRT

I'm closing the issue because the PR that fix it has been merged.
