Unable to mute video when no audio device present on system

### Steps to reproduce

1. Register new user
2. Create new room
3. See video preview works
4. Click video mute button
5. State of video mute button does not alter; video remains unmuted.

Repeatable replication available via trafficlight test (test not complete so not committed yet)

### Outcome

#### What did you expect?
Even if no audio device present, to be able to mute video device.

#### What happened instead?
Video device could not be muted.

Logs say:
```
* Trafficlight asked to execute action "set_mute", data = {"video_mute":true}:
Action for "set_mute" found in action-map ✔
Video state currently unmuted, clicking.

PP0: GroupCall 1684422238299arroN3r6MjWal2Bf setLocalVideoMuted() no device or permission to receive local stream, muted=true
```
And the icon state doesn't change; which fails the test.
