As documented in napi_wrap section, the returned reference must be deleted with `napi_delete_reference` in response to the finalize callback, in which `napi_unwrap` and `napi_remove_wrap` is not available. When the reference needs to be deleted early, it should be deleted after the wrapped value is not accessed with `napi_unwrap` and `napi_remove_wrap` too. This test is previously added in response to duplicating the test https://github.com/nodejs/node-addon-api/blob/main/test/objectwrap_constructor_exception.cc in the node-addon-api. As Napi::ObjectWrap<> is a subclass of Napi::Reference<>, napi_remove_wrap in the destructor of Napi::ObjectWrap<> is called before napi_delete_reference in the destructor of Napi::Reference<>.

As documented in napi_wrap section, the returned reference must be
deleted with
napi_delete_referencein response to the finalizecallback, in which
napi_unwrapandnapi_remove_wrapis notavailable.
When the reference needs to be deleted early, it should be
deleted after the wrapped value is not accessed with
napi_unwrapand
napi_remove_wraptoo.This test is previously added in response to duplicating the test
https://github.com/nodejs/node-addon-api/blob/main/test/objectwrap_constructor_exception.cc
in the node-addon-api. As Napi::ObjectWrap<> is a subclass of
Napi::Reference<>, napi_remove_wrap in the destructor of
Napi::ObjectWrap<> is called before napi_delete_reference in the
destructor of Napi::Reference<>.
This fix is intended to fix the use-after-free problem in #44141.
