Jest Worker swallows exception with UnhandledPromiseRejectionWarning

🐛 Bug Report

When running a task inside a Jest Worker, exceptions get swallowed and raised as UnhandledPromiseRejectionWarning, making it hard to debug.

To Reproduce

Clone this repo, and run the following:

yarn
yarn run production

Expected behavior

I should see an exception from css-minimizer-webpack-plugin complaining about this line (wrong variable interpolation). Instead, all I see is:

UnhandledPromiseRejectionWarning: DataCloneError: function destructLexErrorInfo() {
          // remove cyclic references added to error info:
          // info....<omitted>... } could not be cloned.
    at reportError (/Users/mattiagiuffrida/Development/sensortower/overseer/node_modules/jest-worker/build/workers/threadChild.js:100:32)
    at reportClientError (/Users/mattiagiuffrida/Development/sensortower/overseer/node_modules/jest-worker/build/workers/threadChild.js:84:10)

An issue has already been raised in https://github.com/webpack-contrib/css-minimizer-webpack-plugin/issues/113, but the team there advised this is an issue with jest-worker.
