## Rationale for this change

WIthout this fix running clickbench with limited ram panics:

```sql
SELECT
"UserID",
extract(minute FROM to_timestamp_seconds("EventTime")) AS m, "SearchPhrase", COUNT(*) FROM 'benchmarks/data/hits_partitioned' GROUP BY "UserID", m, "SearchPhrase"
ORDER BY COUNT(*) DESC LIMIT 10;
```

```shell
andrewlamb@Andrews-MacBook-Pro-3:~/Software/datafusion2$ cargo run --bin datafusion-cli -- -m 1G -c "SELECT \"UserID\", extract(minute FROM to_timestamp_seconds(\"EventTime\")) AS m, \"SearchPhrase\", COUNT(*) FROM '/Users/andrewlamb/Software/datafusion/benchmarks/data/hits_partitioned' GROUP BY \"UserID\", m, \"SearchPhrase\" ORDER BY COUNT(*) DESC LIMIT 10;"
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.40s

 This command causes a panic

  cargo run --bin datafusion-cli -- -m 1G -c "SELECT \"UserID\", extract(minute FROM to_timestamp_seconds(\"EventTime\")) AS m, \"SearchPhrase\", COUNT(*) FROM '/Users/andrewlamb/Software/datafusion/benchmarks/data/hits_partitioned' GROUP BY \"UserID\", m, \"SearchPhrase\" ORDER BY COUNT(*) DESC LIMIT 10;"

  It panics in ByteViewGroupValueBuilder::take_buffers_with_partial_last

  I think the problem happens due to a bug in the take_n implementation
