Server should not crash when an invalid event is applied on the server

```
Failed to apply event {
  _id: 'Exit',
  _tag: 'Failure',
  cause: {
    _id: 'Cause',
    _tag: 'Fail',
    failure: InvalidEventError { _tag: 'InvalidEventError' }
  }
}

            throw new Error('Invalid event');
                  ^

Error: Invalid event
