TS config for tests of example-app-karma is broken

[shaman-apprentice]

Bug

Expected Behavior

GIVEN a fresh checkout of this repository with a fresh npm i
WHEN adding a debug console.log to a test from example-app-karma
THEN its tests pass

Actual Behavior

The tests fail to run, due to missing typescript types

Notes

• Without any change the tests are not run due to cache
  
• Might be related to test not working #354?
• I will prepare a PR to fix this
