This change folds the removal of the in-progress snapshot entry into setting the safe repository generation. Outside of removing an unnecessary cluster state update, this also has the advantage of removing a somewhat inconsistent cluster state where the safe repository generation points at `RepositoryData` that contains a finished snapshot while it is still in-progress in the cluster state, making it easier to reason about the state machine of upcoming concurrent snapshot operations.
