Wrong return type from operation on custom tensor inside registered hook

### 🐛 Describe the bug

Hi!

I implemented some subclass of pytorch tensor in my applications, and need to operate such custom tensors in a call back function hooked to a tensor’s backward pass. However, i found that any operation of such custom tensor would yield torch tensor inside such hooked callbacks, while i am hoping them to return tensor of the custom class.

A minimal example:
```
import torch

class CTensor(torch.Tensor):
    pass

def hook(grad):
    print('within hook:', type(a[:1]))

a = CTensor([1,2,3]).requires_grad_()
b = CTensor([1,2,3]).requires_grad_()
b.register_hook(hook)

c = b.sum()
print('outside hook:', type(a[:1]))

c.backward()
```
This prints
```
outside hook: <class '__main__.CTensor'>
within hook: <class 'torch.Tensor'>
```

However,I suppose the slicing operation inside the hook() should also return tensor of my custom class CTensor. Is this a bug, or something expected?
Thanks!!
