test(transaction): add some test cases for nested transactions

Test whether we can start two nested transactions ... 1. ... complete them and see the result in the database 2. ... rollback the outer one after completing the inner one, and see that the result is _not_ in the database. 3. ... roll back the inner one and see if the result of the outer one is in the database after completing.
