Update: I found a way to unit test this and a good thing I did too. The
approach I had built wasn't really working since the query method I used closed
connection. That's fixed now. Furthermore the unit test revealed that such
update scripts can easily cause deadlocks at the DB level. These will be rolled
back, but the client needs a good way to catch them, which is why I added the
`RolledBackUpdateException`.
