Ensure BakedQuery is cloned before we add options to it

Fixed bug in new polymorphic selectin loading where the BakedQuery used
internally would be mutated by the given loader options, which would both
inappropriately mutate the subclass query as well as carry over the effect
to subsequent queries.
