luci-base: fix refresh in initNetworkState
Stale state is kept around due to the _init = _init
(re)assignment, and this assignment prevents a refresh.
After running everything through testing, I also
found uci.delete -> uci.remove. I could completely remove
both deleteWifiNetwork functions and still delete
networks, suggesting these go unused. There are no
other references to them anywhere...
Add also pse property, as a follow-up to
