network: load settings for the open networks

iwd was auto-connecting to the open networks despite having
Autoconnect=false flag set in the network configuration file.
This patch enables iwd to load the configuration files for the
open networks during the auto-connect attempt to take advantage
of the Autoconnect flag.
