- lagoon.Transaction, the lagoon:after_commit flush and the immediate
AfterCommit path pass a handle with an empty statement on the write's
connection (Session NewDB+Context, Clauses(), Session NewDB)
- a WithContext query through the handle no longer continues from the
written model's statement (deferred from 11-05)
- TestTransactionAfterCommit/callback_handle_has_a_clean_statement covers
the implicit, plain-transaction and lagoon.Transaction paths
