test: fix compiler warnings in callback-scope

Currently there are two compiler warnings generated from the addons test
callback-scope:

../binding.cc:44:10:
warning: 'Resolve' is deprecated [-Wdeprecated-declarations]
  local->Resolve(v8::Undefined(isolate));
         ^
../../../../deps/v8/include/v8.h:3893:45:
note: 'Resolve' has been explicitly marked deprecated here
V8_DEPRECATED("Use maybe version", void Resolve(Local<Value> value));
         ^

../binding.cc:52:54:
warning: 'New' is deprecated [-Wdeprecated-declarations]
    persistent.Reset(isolate, v8::Promise::Resolver::New(isolate));
                                                     ^
../../../../deps/v8/include/v8.h:3880:42:
note: 'New' has been explicitly marked deprecated here
Local<Resolver> New(Isolate* isolate));

This commit updates the test to use non-deprecated functions.
