Add test to check persistence of newly added pre-linked objects

Added a MockRegionDataPlugin to do in-memory persistence for tests since adding this to OpenSim.Data.Null.NullDataStore doesn't seem appropriate
NullDataStore can do nothing because OpenSim only ever retrieve region objects from the database on startup.  Adding an in-memory store here would be unecessary overhead.
