NotEqual filter not working with DateTime

[Muchiachio]

public class Program
{
    public static void Main(string[] args)
    {
        IQueryable<Model> models = new[] { new Model() }.AsQueryable();

        Console.WriteLine(models.Where("Date != null").ToArray().Length);
    }
}

public class Model
{
    public DateTime Date { get; set; }
}

Throws The binary operator NotEqual is not defined for the types 'System.DateTime' and 'System.String'. This works in System.Linq.Dynamic and System.Linq.

Issue is solved, some unit-tests are also added.

Can you please verify this library ? Or do you want a NuGet to test ?

I confirmed in a library, it's working.
