`setup()` and `teardown()` errors are not logged when invoked from REST API

[na--]

If you run this script:

export const options = {
    paused: true,
};

export function setup() {
    console.log('foo')
    throw new Error('bar');
}

export default function (data) {
}

And execute curl -iX POST 'http://localhost:6565/v1/setup' in another terminal, you would not see the script error bar in the terminal, but you'd see foo.

@na-- I tried to reproduce to fix this bug, but it seems to be fixed.

# Run your script
$ k6 run script.js

# execute curl (in another terminal)
$ curl -iX POST 'http://localhost:6565/v1/setup'
HTTP/1.1 500 Internal Server Error

    }
  ]
}

# my k6 version
$ k6 version  
k6 v0.46.0 ((devel), go1.21.0, darwin/arm64)

@kmtym1998 I think the idea @na-- had was that it should also print the exception in the k6 output, not just in the response to curl

@mstoykov

I see. I would like to try to fix this. Can I work on?
