az monitor app-insights with --output gives no output

## Describe the bug
`az monitor app-insights` with `--output` provides no output, while without `--output` it works fine.

Example command that works:
```
$ az monitor app-insights query -g resource -a name --analytics-query "requests | where url contains '.servicebus.windows.net/t_'" --start-time "2022-02-01" --offset 30d | wc -l
28629
```
Example that doesn't work
```
$ az monitor app-insights query -g resource -a name --analytics-query "requests | where url contains '.servicebus.windows.net/t_'" --start-time "2022-02-01" --offset 30d --output table | wc -l
1
```
