2. Fixing correct error handler tests were previously these would report a false positive isue
3. Fixing recent unit tests to be added as part of the main save method suite
4. Fixing an issue with the tests which didn't clean the user1 entry in the db and so tests following it would fail regardless of the validation
5. Fixing one test to actually be valid use case
