Presto logicalRowExpressions creating wrong DNF form

[jaystarshot]

 @Test
    public void testWrongDnf()
    {
        RowExpression test = new SpecialFormExpression( SpecialFormExpression.Form.OR, BooleanType.BOOLEAN, Arrays.asList(a, b, c, d));

        assertEquals(
                logicalRowExpressions.convertToDisjunctiveNormalForm(test),
                or(or(a, b), or(c, d)),
                "Failed 1,1");
    }

in test
Error

Failed 1,1 expected [OR(OR(a, b), OR(c, d))] but found [OR(a, b)]

This test case fails and logicalRowExpressions is unable to create a proper dnf form. This only happens when the specialFormExpression has > 2 arguments
This seems to be one of the root cause of #22147
