Original GitHub issue: https://github.com/amnezia-vpn/amnezia-client/issues/680

Describe the bug
This error comes from #577. The thing is wgConfigData variable in -[PacketTunnelProvider startWireguard] lacks client_pub_key json value. I don't know yet in what situations this happens but struct decoding fails because of this error. This leads to app being visually connected but it's not.

That was between that PR and dev branch. Now wgConfig struct in -[PacketTunnelProvider startWireguard] has allowedIPs field set to an empty string for some reason. This leads to the same behaviour - app being visually connected but it's not.

I'll see a bit later how exactly this can be fixed.

To Reproduce
Import AWG config and connect. App will show "Connected" state as well as system will show "VPN" badge but it won't be really connected.

Expected behavior
App mustn't pass any invalid json in this part

Smartphone (please complete the following information):

Device: iPhone 8
Version: 16.6.1

Seems like that's invalid in dev branch now...

Reopening as I've investigated some more and found allowedIPs struct field now contains empty string

Still have problems on v4.4.1 and v4.4.2 on iOS - tunnel shown as "Connected" but actually packets did not sent to tunnel interface

while returning back to v4.4.0 fixes the problem
