Regression - http error codes and message not displayed properly on the UI

### Expected Behavior

If an http request fails I expect Insomnia to show the http status code (4xx, 5xx, etc) and the error message in the preview. This used to work but broke recently.

### Actual Behavior

When there is a request failure the http status code is not displayed and an internal error message is shown in the preview. The error message is:
```
message: undefined; stack: Error: message: Cannot read properties of undefined (reading '0'); stack: TypeError: Cannot read properties of undefined (reading '0')
at fn0 (eval at S (file:///Applications/Insomnia.app/Contents/Resources/app.asar/hiddenBrowserWindow-Ci3kk9w5.js:1:664), :12:21)
at eval (eval at S (file:///Applications/Insomnia.app/Contents/Resources/app.asar/hiddenBrowserWindow-Ci3kk9w5.js:1:664), :22:13)
at S (file:///Applications/Insomnia.app/Contents/Resources/app.asar/hiddenBrowserWindow-Ci3kk9w5.js:8:25)
at async file:///Applications/Insomnia.app/Contents/Resources/app.asar/hiddenBrowserWindow-Ci3kk9w5.js:1:346
at port.onmessage (/Applications/Insomnia.app/Contents/Resources/app.asar/preload.js:145:18)
```

Here is a recording of the issue happening when calling an endpoint multiple times until it hits a rate limit (429).


And this screenshots show a 500 that doesn't get properly displayed in preview.
