[release] 5.23.1 - FIX - Dont update internal store if definition is …

…outdated (#468)

### Fixes
- Fixes a bug where we could update the internal store with stale values
(older than the current values in memory). While this was unlikely, now
it wont happen
- Removes secret key from the output logger
- explicitly set sincetime of 0 on first fetch
