Undici crash even when fetch is not used

[syamsudotdev]

Describe the bug
Running Monika with --symonUrl <URL> --symonKey <UUID> --follow-redirects=5 --retryInitialDelayMs=150000 --ignoreInvalidTLS will log errors from undici.

To Reproduce
Steps to reproduce the behavior:

1. monika --symonUrl <URL> --symonKey <UUID> --follow-redirects=5 --retryInitialDelayMs=150000 --ignoreInvalidTLS
2. See error in screenshot

Expected behavior
Running command mentioned above should not log undici errors, as Monika is not provided with --native-fetch flag. Thus not using node.js' fetch API and should not log undici errors.

Got this thought after waking up today: Maybe Monika v1.19.1 isn't running very well with Symon because Monika didn't catch this error, hence breaking the probing mechanism, causing Monika only reported few probes only.
