- All accessors come up in exception state.
- Read-accessors increase counter in init phase

Assertion is gone, but tests still failing

  - EntityOwner has individual counters for both events
  - Adapted all instances of increment/decrementDataFaultCounter
  - Not changed getDataValidity() implementation yet
  - Tests failing

Need to wait until the internal fan out threads have been launched and acquired the testable mode lock before continuing with app starting and testing to avoid race conditions.

- some more code cleaning
