Problem statement:
Padding error with `RandomCrop`
### Describe the bug

Tests are failing because of the following test `TestAugmentationSequential::test_random_crops` possibly introduced by the combination of be104a5 and 3f8e7a3.

Output error:

```python
 if mode.startswith("vertices"):
            batched = boxes.ndim == 4
            if not (3 <= boxes.ndim <= 4 and boxes.shape[-2:] == torch.Size([4, 2])):
>               raise ValueError(f"Boxes shape must be (N, 4, 2) or (B, N, 4, 2) when {mode} mode. Got {boxes.shape}.")
E               ValueError: Boxes shape must be (N, 4, 2) or (B, N, 4, 2) when vertices_plus mode. Got torch.Size([3, 3, 4]).
```

NOTE: This is a major bug, for now test is disabled until this is fixed.

### Reproduction steps

```bash
pytest test/augmentation/test_container.py::TestAugmentationSequential::test_random_crops
```


### Expected behavior

Pass the tests and enable the tests.
