[Bug]: Sign in required after restarting hub since update from 3.12 to 3.16

### What Happened

When restarting Unity Hub, I have to sign in again. I should stay logged in.
The command line output shows errors connecting to kwallet, so I assumes its just dbus permissions missing. See comment.

### How to Reproduce

1. Open Unity Hub
2. Sign in
3. Restart pc or quit hub from the system tray
4. Open Unity Hub again
5. I am not signed in

### Operating System

Fedora Kinoite 43

### Command-line output

```shell

```

### Anything else?

I manually gave permission to communicate with the following sessison busses:
- `org.freedesktop.DBus`
- `org.kde.kwalletd6`

This successfully solved the issue.
