Title: Fix transactions do not get rollbacked in saveAssociated/saveMany

Fixes #2849

Also I have fixed several rollback tests.
Previously, they call rollback() regardless of whether data is valid or not.
(For example, testSaveAllManyRowsTransactionNoRollback will pass even if Post.title is not empty)
