GLib implementation of g_dbus_connection_call_sync() calls g_variant_ref_sink() on the passed @parameters to make sure they have proper reference. If the original reference is floating the g_dbus_connection_call_sync() consumes it, but if it's normal reference it will just add another one. Our mock functions were only freeing the @parameters which is incorrect and doesn't reflect how the real implementation works.
