Previously TableScan struct was requiring a Snapshot to plan files and for empty tables without a snapshot an error was being returned instead of an empty result. Following the same approach of Java [0] and Python [1] implementation this commit change the snapshot property to accept None values and the `plan_files` method was also changed to return an empty stream if the snapshot is not present on on PlanContext.

If there are no data in a table, we should return empty values not throw exception.
