Title: Fix the NotInTransactionException mistake. 

* Pure reads and queries also need to be in transactions in 2.0.
* PlaceboTransaction is a perfectly valid thing for beginTx to return.
* Always remember to close transactions when we are done with them.
* If success() has not been called on a transaction, then it is assumed failed
when it is closed, so there is usually no need to call failure() explicitly.
