super weird bug in docs runner

[tunnckoCore]

For some reason it throws this error, almost always.

No matter which is the package. Super awful for debugging and always forgetting how we can see the actual error. Debugged it few times but... :D It's nothing related to create-jest-runner, there is no problems.

Turns out it was bug it create-jest-runner's one of the onError calls was with wrong signature.
