Disables MinorGC from collecting object wrappers

The current minor GC collects all unmodified wrappers that are not active. It does not take care about references. Hence, it is not safe to mark any object that might contain a reference as not active. Several object wrappers could have references, so disabled collecting them during minor GC.
