some of the QA test suite will fail when attempting to run against the latest unstable, due to things like the following:

• changes in index version behavior from 3.0 to 3.2
• WT as default storage engine will force some tests to fail because of things that work differently or not supported if the test does not specify --storageEngine, like the test for --repair

need to go through each of these and update the tests where necessary so they work when run against either 3.0 or 3.2, or disable any tests in the unstable suite where they do not apply.
