### Bug description
[Expected behavior] and [actual behavior].
For following query
```sql
select a,b from (
select id as a from range(1)
) as t1
full outer join (
select * from ( select id as b from range(2) ) t2 where b > 10
) as t3
```
`vanilla`'s result is
```
0, null
```
but `gluten`'s result is empty.
This is a conner case, the `full join` is tranformed into `cross join`,
`cross join` returns empty if any table is empty.
