[Ndn-lib] ndn-js proxy crash FYI

Team,

it's great to see ndn-js getting used in multiple projects.

ws-proxy is pretty stable on the app boxes... yet last night, after a few
weeks of uptime the ws-proxy on UCLA app box crashed.

ccndstatus indicates route to hub was still up; box appeared normal - ccnd
& route up, online... just no ws-proxy.

The only thing different about this app box, is it's
directly communicating w/ Wentao's latest ndn-js client for BMS/repo data.

I have full packet capture via ws-proxy logging (15MB) if wanted; meanwhile
here's stderr:

/home/localadmin/NDNAppBox/installer/ndn-js/wsproxy/node_modules/ws/lib/WebSocket.js:175
    else throw new Error('not opened');
         ^
Error: not opened
