Removing more than two items from a list

Package version (if known): 0.9.0

## Describe the bug

There seems to be an error when more than two items are deleted from a list:

```
import dictdiffer

before = [{"idx": 1}, {"idx": 2}, {"idx": 3}, {"idx": 4}]
after = [{"idx": 1}]

dd = dictdiffer.diff(before, after)
print(dictdiffer.revert(dd, after))
```

prints

```
[{'idx': 1}, {'idx': 2}, {'idx': 4}, {'idx': 3}]
```

## Steps to Reproduce

Try the code above.

## Expected behavior

It should print

```
[{'idx': 1}, {'idx': 2}, {'idx': 3}, {'idx': 4}]
```

## Additional context

It seems to occur only if more than 2 items are deleted - for 1 or 2 deleted items everything works fine.
