ERR_reason_error_string should only return nullptr if ERR_get_error returned 0, indicating no error.

If there is a guarantee that ERR_get_error will not return 0, this should probably be a CHECK_NOT_NULL(str) instead. (But I don't know if that's the case.)

@tniessen I did wonder about that, but I checked other places that ERR_reason_error_string was called in the Node.js code base and in those places (I think there were 2 others) the code did a nullptr check.


return env->ThrowError(str);
