REPO-1012 : DB builds: Fix a batch of tests that (regularly) fail on SQL Server

- adding retrying transactions for the propertyValueDAO.cleanupUnusedValues() method calls as MS SQL is slow and has problems coping with other threads updating the alf_prop_ tables
   - changed the order of the tests to help reduce other tests failing because of these clean up tests
