* Fix `entity.max`, `entity.min`, `entity.all` and `entity.reduce` for multi-entities simulations.
- This issue was not affecting simulations with several persons in a _single_ entity
- These operators were not working as expected in case the persons of the simulation were not sorted by entity id in the persons vector. For instance:
- First household: [Alice, Bob]
- Second household: [Cesar]
- Persons vector: [Alice, Cesar, Bob]
