Some AbstractRecord test classes return invalid TwoPhaseOutcome values

The test classes

arjuna/tests/classes/com/hp/mwtests/ts/arjuna/atomicaction/AtomicActionUnitTest.java
arjuna/tests/classes/com/hp/mwtests/ts/arjuna/atomicaction/TxStatsSystemErrorUnitTest.java

contain inner class implementations of AbstractRecord that return invalid values from the action lifecycle methods. For example:

public int topLevelCommit() {return 0;}

which maps to TwoPhaseOutcome.PREPARE_OK which is wrong.
