Bug#1065365: Fix compatibility with NM 1.44 and above

[Michael Biebl <biebl@debian.org>]

Source: networkmanager-qt
Version: 5.107.0-1
Severity: important
Tags: patch upstream

Dear Qt/KDE maintainers.

I had several users report problems with plasma-nm, which is broken once
NetworkManager.service is restarted (which e.g. happens on package
upgrades).

This was e.g. filed as
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1053707
or
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1065099

After a bit of digging, I think the issue is the one described at
https://bugs.kde.org/show_bug.cgi?id=471870#c19
https://invent.kde.org/frameworks/networkmanager-qt/-/commit/d9a938ddbfb5800503935926301ff2865ab77a6d

Please consider cherry-picking that patch for Debian.
