Fail on execute Test

[GitMeLyK]

Hello, i have a question to replicate this test.

       Infrastructure.Linq.Processors -> void TrackUnseenEntities()
       Infrastructure.Linq.Processors -> void  RefreshEntityIfMarkedAsNoChanges()

How come these two tests fail with "System.ArgumentException : Type is already registered as a BsonClassMap" if I start each test individually. I tried debugging I noticed that the entity map can not locate the primary key given by the id. But the thing that leaves me a bit like this, is that if I start the whole set of tests of this class they are successful. ?!?. If the same tests are run after running in order before the DontRefreshEntityIfMarkedForUpdate() tests Unseen... and Refresh... works correctly, but what changes? There is something that makes you get the right context in Tracking first?.

Hey @GitMeLyK - thanks for raising the issue! It looks like you've found a very subtle bug with when mapping applies in those tests.

MongoFramework (via the EntityMapping class) wraps the MongoDB driver's BsonClassMap logic. This works fine for the most part except if something triggers a BsonClassMap to be generated directly. Entity tracking works by creating an EntityEntry object with the value but, as part of trying to discover any updates, it creates a BsonDocument. When that is called, it is triggering the generation of a BsonClassMap but there isn't a corresponding entity definition in EntityMapping for MongoFramework.

The fix for it is basically introducing one line of code during the EntityEntry constructor to ensure the entity type is registered.
