fix(journal): preserve trans_id_reference_number

We now remember the trans_id_reference_number when we create new lines
in a transaction.  This means we no longer error when trying to add new
lines to a transaction.

Note that we still need to add a test.

Partially addresses Third-Culture-Software#3536.
