Issue: Backwards compatibility broken for cached datasets that use `.filter()`
State: closed
Labels: name: bug

## Describe the bug
After upgrading to datasets `1.12.0`, some cached `.filter()` steps from `1.11.0` started failing with 
`ValueError: Keys mismatch: between {'indices': Value(dtype='uint64', id=None)} and {'file': Value(dtype='string', id=None), 'text': Value(dtype='string', id=None), 'speaker_id': Value(dtype='int64', id=None), 'chapter_id': Value(dtype='int64', id=None), 'id': Value(dtype='string', id=None)}`

Related feature: https://github.com/huggingface/datasets/pull/2836

:question:  This is probably a `wontfix` bug, since it can be solved by simply cleaning the related cache dirs, but the workaround could be useful for someone googling the error :) 

## Workaround
Remove the cache for the given dataset, e.g. `rm -rf ~/.cache/huggingface/datasets/librispeech_asr`.

## Steps to reproduce the bug
1. Delete `~/.cache/huggingface/datasets/librispeech_asr` if it exists.

2. `pip install datasets==1.11.0` and run the following snippet:

```python
from datasets import load_dataset

ids = ["1272-141231-0000"]
ds = load_dataset("patrickvonplaten/librispeech_asr_dummy", "clean", split="validation")
ds = ds.filter(lambda x: x["id"] in ids)
```
3. `pip install datasets==1.12.1` and re-run the code again

## Expected results
Same result as with the previous `datasets` version.

## Actual results
```bash

Hi ! I guess the caching mechanism should have considered the new `filter` to be different from the old one, and don't use cached results from the old `filter`.
To avoid other users from having this issue we could make the caching differentiate the two, what do you think ?

If it's easy enough to implement, then yes please 😄  But this issue can be low-priority, since I've only encountered it in a couple of `transformers` CI tests.

Well it can cause issue with anyone that updates `datasets` and re-run some code that uses filter, so I'm creating a PR

I just merged a fix, let me know if you're still having this kind of issues :)

We'll do a release soon to make this fix available

Definitely works on several manual cases with our dummy datasets, thank you @lhoestq !

Fixed by #2947.
