networks: tweak detection of configured wireless interfaces in TOS 6.0
In certain conditions, configured and working wifi interfaces are displayed in "Unassigned"/none_networks category in reforis "Interfaces" page. Guest wifi is detected correctly, i.e. it is in Guest category.
See: https://forum.turris.cz/t/turris-os-6-0-is-now-in-hbt-testing-branch/17776/14
For example:
- after wifi settings reset in TOS 6.0
- on fresh TOS 6.0 install from medkit
Older configuration (upgrade from TOS 5.x to 6.0) should work fine.
This is not an issue of reforis, but the backend that provides the data.
