BGE: Fix T35188: Duplicate an instance of group.
This behavior caused a double free.
Before when we duplicated an instance of a group the new instance keep the
pointer of the group but was not added in the group instance list (normal).
And during the object deletion we tried to remove the object in the instance
list but anyways if it failed decrement the reference count.
Set the group and the instance list to NULL in ProcessReplica avoid these kind
of problems.
