Using `group` causes panic in backend

__Steps to reproduce:__

1. probably have to set up data in a very specific way -> no idea what might have caused it
2. append `group` at the end of a query...

```
from(bucket:"telegraf")
|> range(start: 2022-03-17T12:54:59Z, stop: 2022-03-17T12:55:03Z)
|> filter(fn: (r) => r["_measurement"] == "DataSeries")
|> pivot(rowKey:["_time"],
columnKey: ["_field"],
valueColumn: "_value")
|> group(columns: ["dataSeriesId"])
```

__Expected behavior:__
Tables from the previous result are grouped into one table or an error message describing the problem is shown.

__Actual behavior:__
```
a panic has occurred: /api/v2/query?orgID=[redacted]: interface conversion: array.Interface is *array.Binary, not *array.Int64
```

__Environment info:__

* System info: Linux 5.15.28-1-MANJARO x86_64
* InfluxDB version: 2.0.7 (Docker)
* Other relevant environment details: Docker 20.10.12 running `influxdb:alpine@sha256:7630ad8caae177fe5442cce81068b944c13e2daa7ec289d6d3710b836824cd79`

Start by reproducing the provided Flux query against the reported InfluxDB environment, then inspect the stack frames in flux/arrow/table_buffer.go and flux/csv/result.go. Trace how the grouped result reaches CSV encoding and add coverage for this query; done means it returns grouped tables or a descriptive error without panicking.
