The tests have been modified to work under NUnit 2.4.6
(the one currently used in the project).
They will also work with NUnit 2.5+ as is, but will look better
if you #define NUNIT25 for them.
The problem was that some tests relied on prior tests
to leave the DB in a particular state, but the test class
cleared the DB every time. The affected tests have been
merged into one to remove the dependencies.
tested on all 3 Dbs, all tests green.
