When we're finalizing, the remote settings instance might already be gone and thus we can't list connections. In particular this happens at panel finalization resulting in the following warning: libnm-glib-CRITICAL **: nm_remote_settings_list_connections: assertion 'NM_IS_REMOTE_SETTINGS (settings)' failed because cc_network_panel_dispose() unrefs the remote settings object before all the NetDevice instances are finalized. Since we only need to list connections on finalize to disconnect a signal we can instead use g_signal_connect_object() and keep the connections that we're keeping track of in a hash table instead of g_object_set_data(). https://bugzilla.gnome.org/show_bug.cgi?id=749850
