Make `requestDriver` more resilient to errors

[joschi]

If the async request performed in requestDriver.makeDriver() fails, it would call the callback function with empty parameters but then continue the execution which can lead to the following error and crash of Fredy:

Error while trying to scrape data. Received error: Request failed with status code 504
/fredy/lib/services/requestDriver.js:25
    if (typeof result.data === 'object' && url.toLowerCase().indexOf('scrapingant') !== -1) {
                      ^

TypeError: Cannot read properties of undefined (reading 'data')

@joschi a test is failing. I don't think this has something to do with your change, but can you have a look?

@orangecoding Looks like an intermittent error with wg-gesucht.de which has been fixed by now.

Maybe you could re-run the tests on this PR.
