Jest: Jest did not exit one second after the test run has completed.

🐛 Bug Report

I've updated jest to the latest version because of the bug with NodeJS version 11.11.0. All tests do success but it prompts the following message:
"Jest did not exit one second after the test run has completed"

To Reproduce

Steps to reproduce the behavior:

1. install the latest version of jest

Expected behavior

Tests should work as before.

The issue is tied to node-notifier bug in 5.4 version :- https://github.com/mikaelbr/node-notifier/pull/271

There is already a jest bug similar to it - https://github.com/facebook/jest/issues/7890

@SimenB thanks to this issue lol it wasted my whole day later to realise notify:true on jest config was culprit lol :(
