Internally used to handle local snapshots.

Method Summary
	`disableSnapshotRefCounting(self)` Overrides 'SnapshotsHandling.SnapshotsTable.disableSnapshotRefCounting()'
	`isSnapshotRefCountingEnabled(self)` Return false: we do not care about snapshot reference counting here, since the snapshots are only used when saving changes and are discarded after the transaction finishes.
