systemtray: Fix race in DBusServiceObserver
When a service appears right after the ListNames() call finished, but
before the QDBusPendingCallWatcher is set up, the ::serviceRegistered
signal will be queued before the ListNames() response. As a result,
the service will be ignored by DBusServiceObserver.
Switching to QDBusInterface::callWithCallback() ensures that the
result slot is queued as soon as the response arrives, thus avoiding
the race.
Credits go to Sam Edwards for identifying the problem in
