I think I know what causes the KDE Connect behavior. The CMake code
calls 'ecm_find_qmlmodule(org.kde.people 1.0)', which results a call to
'qmlplugindump org.kde.kpeople 1.0' which causes parts of the KPeople
code to be executed (PersonsModel in particular) which does some DBus
things that then trigger dbus-daemon.

As a stopgap solution to make the CI operational we can remove that
ecm_find_qmlmodule call.

In terms of a proper solution there was a recent effort to remove the
mandatory DBus dependency from KPeople on Windows
( Perhaps
we should instead fully disable all DBus code in KPeople on Windows
instead, given that the usefulness is questionable.
