core: simplify 'is null' sql expression

The original logic generates conditional expressions like

(tab.col = null or tab.col is null)

tab.col = null never evaluates to true on known sql database
engines, so the generated expression can be simplified with this.
The new generated condition will be just

(tab.col is null)
