additional data manager serialization tests need to move here #239
Description
#232 caused a regression fixed by #237.
This was ultimately caused by the fact some unit tests are located in the service library when they should be here. Namely the additional data manager unit tests (and maybe all the tests in the same folder).
Having earlier, reliable feedback would have caught this regression. It'll also avoid duplicating the tests between v1 and beta.
