The test data was wrong, and was triggering the work-around code that
MDL-32062 introduced. I fixed the test data.
Also, I fixed one of the tests, that had been broken.
1/ type/match/tests/walkthrough_test.php - tests are failing randomly, looks like some weird randomisation is going on there - see TODOs
2/ type/multianswer/tests/upgradelibnewqe_test.php contains invalid expected value - see TODO
