referential_spec(duplicate referential): Check that lock gets released

Add an extra referential to the test and check that it gets saved to
confirm that the table lock gets released at the end of the transaction.
Not sure if this is actually necessary to verify, but wanted to make
sure before I had gone and read the Postgres docs
(https://www.postgresql.org/docs/9.4/static/explicit-locking.html#ADVISORY-LOCKS).
