fixes e2e tests (#3817)

- fix newsfeed and calendar e2e tests so they don't need `--forceExit`
anymore
- `--forceExit` should stay in test runs to avoid running until test
limit in case of errors
- remove mocking console, not needed anymore
- configFactory-stuff should not run in browser (otherwise we get errors
`[ReferenceError: exports is not defined]`)
