SUMMARY

KOrganizer requests to a DAV server are sent without User-Agent header.
This header should be present as it can be useful for troubleshooting client issues.

STEPS TO REPRODUCE
1. Have KOrganizer configured with a DAV Resource.
2. Perform any activity that will create a request to the DAV server.
3. Observe DAV server logs.

OBSERVED RESULT

```nginx access.log
<scrubbed> - <username> [28/Dec/2022:13:09:05 <scrubbed>] "PROPFIND /<username>/<scrubbed>/ HTTP/1.1" 207 278 "-" "-"
```

EXPECTED RESULT

DAVx⁵ (on android) behavior:
```nginx access.log
<scrubbed> - <username> [27/Dec/2022:02:27:01 <scrubbed>] "PROPFIND /<username>/<scrubbed>/ HTTP/2.0" 207 401 "-" "DAVx5/4.2.6-ose (2022/12/12; dav4jvm; okhttp/4.10.0) Android/13"
```
