make do -i works with liststream (#7889)
# Description

Fixes: #7874 

It's because `do -i` doesn't handles `Pipeline::ListStream`
data(especially there is Value::Error inside the stream)

To fix it, we need to iterate through `ListStream`, check if there is
`Value::Error`. If so, just returns `Pipeline::empty()`

# User-Facing Changes

```
help commands | find arg | get search_terms | do -i { ansi strip }
```

No longer raises error.

# Tests + Formatting

Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used -A
clippy::needless_collect` to check that you're using the standard code
style
- `cargo test --workspace` to check that all tests pass

# After Submitting

If your PR had any user-facing changes, update [the
documentation](https://github.com/nushell/nushell.github.io) after the
PR is merged, if necessary. This will help us keep the docs up to date.
