Repository to reproduce error registering error handler

This issue appeared after upgrading functions from node 10 to node 14. Cannot use Sentry because of it - it registers uncaughtException handlers.

To reproduce issus:

1. Run functions shell

npm run build
firebase functions:shell --project <specify you project id here>

2. Add some uncaught exception handler

process.on("uncaughtException", function(err) {
    console.error("uncaughtException");
})

3. See error:

Uncaught:
TypeError [ERR_INVALID_REPL_INPUT]: Listeners for `uncaughtException` cannot be used in the REPL
