SQL/JSON: Fix default ON ERROR behavior for JSON_TABLE

Browse Source 
Use EMPTY ARRAY instead of EMPTY.

This change does not affect the runtime behavior of JSON_TABLE(),
which continues to return an empty relation ON ERROR. It only alters
whether the default ON ERROR behavior is shown in the deparsed output.
