Render NEGATING_SIMPLE_PROPERTY as IS NOT NULL when argument value is null.

Browse Source 
When a query method uses NEGATING_SIMPLE_PROPERTY and the argument is null, the generated query now uses `IS NOT NULL` instead of `<>`. This ensures consistent behavior when handling null values across queries.
