In order to pickle a context object which refers to an active _TransactionContextTLocal, we have to use __reduce__ so that no database, engine, or session state is pickled, and only a constructor remains. Upon unpickling, the constructor will install a new, empty _TransactionContextTLocal on the new context, as is appropriate since this is a totally different context object than the original one.
