Set selecteNode to null break the tree

[cgarnier]

Hello, When a put selectedNode to null i have an issue.

[yoavaa]

that's strange. In the example (http://wix.github.io/angular-tree-control/#selected) it works. Have you tried using undefined instead of null?

[cgarnier]

yes, undefined works.

I have a lot of error when i try to put something not in the tree in the expandedNodes. I know that what is in this array should be in the tree :D But it should be great if in this state, module jsut raise an exception.

Same as here (#194) where you can find the fix.
