+Subject: Fix property changes being missed immediately after an obejct is
+ added
+
+Fix race condition when property changes may be missed if the property
+is changed immediately after the object is created.
+The issue was that the connection to PropertyChanged signal was
+created only after interfacesAdded signal was fired, which may have
+already been too late.
+This fixes it with connecting to PropertyChanged signal on all paths
+in Manager::init().
+
