PV trace groups
How to reproduce:
1. Remove ~/.config/sigrok/PulseView.conf to start with a clean slate.
2. Start "pulseview" (no options)
3. Open the file uart/voltcraft_vc940/voltcraft_vc940_multiple_modes.sr from sigrok-dumps.
4. Ungroup the default trace group, add two new ones, including a nested one (see screenshot).
5. Close PulseView.
6. Start "pulseview" (no options) again. Expected result: The trace groups are restored (but they're not).
