The bmx6-info script will return null when no tunnels are known to BMX6.
However, the "Graph" and the "Tunnels" pages expect a JSON structure with an
array of tunnels. In case no tunnels are known to BMX6, bmx6-info now returns
'{ "tunnels" : [] }'.

The JavaScript code of the network graph tried to fetch the topology from
%HOST/cgi-bin/luci/status/bmx6/topology, but the topology entry is now located
at admin->network->BMX6 (i.e., %HOST/cgi-bin/luci/admin/network/BMX6/topology).
