unique validator and hierarchic selector complete #8476

`NaturalAbstractModelService.count()` does not necessary complete
anymore (because `getPartialVariablesForAll()` may not complete). So
usages of that method must be careful about it and most likely use the
`first()` operator if they expect the observable to
complete.

Otherwise, `unique` validator will never complete and Angular will never
show errors. And the hierarchic selector will never show arrows to open
children.
