Proper handling of IS NULL and IS NOT NULL when multiple conditions are used

[dnnancy]

SELECT Name FROM Customer
WHERE telephone IS NOT NULL
  AND email IS NULL
  AND TwitterId IS NULL

When parsing the above SQL script, the WHERE condition is evaluated as a CriteriaExpression, with the left part being "telephone" and the right part being "NOT NULL AND email IS NULL AND TwitterId IS NULL".

Thanks for the great library.

Please provide a failing test to clarify this issue. I'm not sure what the problem is

Thanks
