How to listen to finish of a write stream if requests were retried?

I have:

```
return new Promise(resolve => {
request(options)
.pipe(fs.createWriteStream(fileName))
.on("finish", function () {
console.log("The file should be completely written here");
resolve(fileName);
});
});
```

and I expected the `finish` to only be emitted if one of my retryable requests went through.

Instead, if there is a retry, the `finish` will be emitted already for the first request and resolve the promise prematurely.

I want to resolve my Promise if and only if one request was successful and the writing to the stream finished with the content. How do I achieve that?
