Preemptively make sure that the apiObject's properties are equal when adding them to the ChangesBuzz

[joantune]

When adding SyncEvent's to the changesBuzz, make sure that if the origin universe is equal, the apiObject of all of those events that may already exist for that given DSIObject, are the same, if they aren't, it means that that object meanwhile changed (between SyncEvent) generations, and the Sync needs to be redone. This way, we can avoid having less exceptions sent when applying the ChangesBuzz.

Alternatively, check this only when processing the ChangesBuzz (before any change is made)
