Make 'Unhandled Rejection' error more prominent

Contribution

• [ ] I'd be willing to implement this feature (contributing guide)

Describe the user story

If you forget await somewhere you'll probably get the Unhandled Rejection and all your tests will be stopped.

At the moment the error looks like:

Terminating on critical error: Unhandled Rejection in testplane:worker:2083:
Promise: {}

Most of the time it is located in the middle of the test log and it is hard to understand that all of your tests were stopped because of it.

Describe the solution you'd like

Make the error message more dramatic:

————————————————————————————————————
CRITICAL ERROR OCCURED. TERMINATINING ALL TESTS.
Unhandled Rejection in testplane:worker:2083:
Promise: {}
————————————————————————————————————
