`resume()` fails if file does not exist.

[jwalton]

The documentation for resume() says: "resume the downloading if supported, if not it will start from the beginning". I assumed this meant I could just call resume() instead of start() to start downloading a file if it isn't there, or to continue downloading the file if it isn't. But, if you try:

const { DownloaderHelper } = require('node-downloader-helper');
const dl = new DownloaderHelper('https://proof.ovh.net/files/1Gb.dat', __dirname, {
    resumeIfFileExists: true,
    removeOnStop: false,
    removeOnFail: false,
});

dl.on('end', () => console.log('Download Completed'));
dl.on('error', (err) => console.log('Download Failed', err));
dl.on('progress', ({ downloaded, total }) => console.log(`Got ${downloaded}/${total}`));
dl.resume().catch((err) => console.error(err));

This will fail with:

TypeError: Cannot read properties of null (reading 'resolve')
