ModemManager: fix auto-config

May just work with a newer version after #54

nmcli connection modify --temporary lte gsm.auto-config yes

Seems to be a NetworkManager issue. Changing the yes/no values makes the warning go away, but doesn't actually get the config to be read properly. Verbose logging doesn't show any more issues.

keyfile: connection.autoconnect: invalid setting: Key file contains key “autoconnect” which has a value that cannot be interpreted.
keyfile: gsm.auto-config: invalid setting: Key file contains key “auto-config” which has a value that cannot be interpreted.
keyfile: gsm.home-only: invalid setting: Key file contains key “home-only” which has a value that cannot be interpreted.

Got the bottom of this:

• gsm.auto-config doesn't work if any of the other GSM connection settings are specified
• gsm.home-only=no doesn't work, need to just exclude it from the config when roaming is allowed
