CriteriaBuilder does not support nested fetch paths when paginating

When using `CriteriaBuilder.fetch()` with nested paths the join fetches are not present in the object query with pagination.
As a workaround, the subpaths have to be passed to `fetch()` individually, but this shouldn't be necessary:
Won't work with pagination:
```java
cb.fetch("document.owner")
```
Workaround:
```java
cb.fetch("document", "document.owner")
```
