.include() fails to include parents when trying to build a tree structure of nodes

[GoogleCodeExporter]

With this:

@BelongsTo(parent = Node.class, foreignKeyName = "parent_id")
public class Node extends Model { }

then this code:

Node.findAll().include(Node.class)

will include the child nodes but not the parents. 
(using findAll is a silly example here, but it would reproduce the bug)

this should be easy to fix, seems you are using a table for a tree structure.

Thank you Igor. 

I was looking over the change to learn more about AJ internals and noticed this 
in the test:

   Node parent1 = sedan1.parent(Node.class);
   Node parent2 = sedan1.parent(Node.class);

   //should return cached parent in both cases
   a(parent1).shouldBeTheSameAs(parent2);

Did you mean to select parent2 from a different location than parent1? Its 
running the same code path for both sides of the comparision. Maybe its what 
you intended, just wasn't quite clear to me from looking at it that it is.

Thanks again!
Evan
