We are using system.rollback_to_snapshot to rollback a table. It works fine
as long as the parent_id exists.
After doing first insert into the table, there is no way to rollback to the
original state of the table.
```
spark-sql> select * from hive_prod.default.test_iceberg.history;
2022-06-27 17:05:26.985 8757768064614539325 NULL true
```
The first history snapshot has NULL as parent id.
```
spark-sql> call
hive_prod.system.rollback_to_snapshot('hive_prod.default.test_iceberg', NULL);
Error in query:
no viable alternative at input 'NULL)'(line 1, pos 81)
```
Is there a way or do I have to delete all rows from the table?
