Extend effect dep validation to handle pruned memoization

Extends the validation that effect deps are memoized to handle an additional 
case that @gsathya  pointed out: when a dependency has a reactive scope but that 
scope ends up being pruned. We track reactive scopes which actually exist in the 
ReactiveFunction, and reject useEffect deps that have an associated reactive 
scope but where that scope does not exist (bc it got pruned).
