The ordination in the QGC combobox for camera selection is inconsistent

[joaoantoniocardoso]

Originally from https://github.com/bluerobotics/BlueOS-docker/issues/1011:

Expected Behavior

The order should be consistent, possibly alphabetically sorted.

Current Behavior

Every time I restart QGC the order of the cameras is shown differently.

Steps to Reproduce:

1. Setup multiple MAVLink cameras (I personally recommend mavlink-camera-manager t3.6.2)
2. Open QGC, take note of the order on the combobox camera selection
3. Restart QGC many times, the order will be different.

System Information

• Operating System: Arch Linux
• QGC Version: tested with AppImage v4.2.3, but should happen with any other too.
• QGC build: AppImage downloaded from here
• Flight Controller: Pixhawk 1
• Autopilot (with version): ArduPilot (Submarine) 4.2.0 (DEV)

I can fix it after my PR #10349 will go into master. I made some fixes and tidy ups so fixing this issue is not a problem for me. But I want to wait for my PR to be merged.
