Persistence of printer broken in Tails 0.23
Originally created by @mercedes508 on #6959 (Redmine)
Persistence of printer does not work in Tails 0.23.
Here is how I reproduced that bug:
1. Boot Tails 0.23, create & enable persistence, select printers and
few other persistent settings
2. Reboot
3. Enable persistence
4. Add printers (2 actually) and modify other settings that are
persistent as well
5. Reboot
6. Printers are not there anymore, but modified settings from 4. are
saved.
