Merge sub_cent_transaction plan item into transactions

Since none of this is deployed or tagged yet, there's no reason for the overly
complex alter table schenanigans.  We have to leave the empty plan item though,
since it's in the git history and otherwise sqitch rebase would break

Will get the hang of this tooling!
