Review Comment:
Shouldn't it also pick up the existing deletes?
Something like:
```
List<DeleteFile> existingDeletes = task.existingDeletes();
List<DeleteFile> addedDeletes = task.addedDeletes();
List<DeleteFile> deletes =
ImmutableList.<DeleteFile>builder().addAll(existingDeletes).addAll(addedDeletes).build();
```
without this I noticed that it can lead to null pointer exceptions when
there as an overwrite snapshot which has existing deletes in it.
