Add test for temporal referential integrity

This commit adds an isolation test showing that temporal foreign keys do
not permit referential integrity violations under concurrency, like
fk-snapshot-2.  You can show that the test fails by passing false for
detectNewRows to ri_PerformCheck in ri_restrict.
