[substrait] [sqllogictest] Unsupported producing row from empty relation

[gabotechs]

Describe the bug

~1800 sqllogictest cases are failing in Substrait round-trip mode because of the following error:

query failed: DataFusion error: This feature is not implemented: Producing a row from empty relation is unsupported

To Reproduce

cargo test --test sqllogictests -- --substrait-round-trip aggregate.slt:387

Expected behavior

The sqllogictest passes in Substrait round-trip mode

Additional context

This is part of a broader initiative to improve the reliability of Substrait-to-DataFusion logical plan conversions.
