Ido*sqlConnection#InternalDeactivateObject(): mark object inactive also in memory

Previously:
1. You delete an object from a config file
2. You reload Icinga
3. Icinga fetches all objects and whether they're active from the IDO
4. Icinga recognizes that the just deleted object doesn't exist anymore
5. Icinga marks it as inactive in the IDO, but not in memory
6. You re-create the just deleted object via API
7. Icinga still thinks it's active and doesn't activate it - it's invisible
