Title: Fatal error in CategoryManager

When making a call to getRootCategoriesPager or getSubCategoriesPager methods from the CategoryManager we obtain the following error:

```
ContextErrorException: Warning: Missing argument 1 for Doctrine\ORM\EntityRepository::createQueryBuilder()
```

The patch fixes this problem.
