Fix behavior of AND CHAIN outside of explicit transaction blocks
When using COMMIT AND CHAIN or ROLLBACK AND CHAIN not in an explicit
transaction block, the previous implementation would leave a
transaction block active in the ROLLBACK case but not the COMMIT case.
To fix for now, error out when using these commands not in an explicit
transaction block. This restriction could be lifted if a sensible
definition and implementation is found.
