Controller name and directive name swapped: Controller 'fooBar', required by directive 'uiTreeNodes', can't be found!

I'm getting an error like this:

```
Controller 'fooBar', required by directive 'uiTreeNodes', can't be found!
```

`fooBar` is my own directive
`uiTreeNodes` is a directive (and a controller) in https://github.com/JimLiu/angular-ui-tree

I'm using 1.3.0-beta.5

it looks like strings have been swapped
