Issue: ENOENT, no such file or directory 'undefined/
When running `ember watson:convert-ember-data-model-lookups`, I get this:

```
ENOENT, no such file or directory 'undefined/'
Error: ENOENT, no such file or directory 'undefined/'

```

Could it have anything to do with the fact that I'm using a POD structure?
