Random crash, maybe with a unfinished request

[dreignier]

Sometime the cgstats nodejs program crash with this stack :

/home/dreignier/cgstats/cgstats.js:190
      resolve(body.success);
                  ^

TypeError: Cannot read property 'success' of undefined
    at Request._callback (/home/dreignier/cgstats/cgstats.js:190:19)
    at Request.self.callback (/home/dreignier/cgstats/node_modules/request/request.js:198:22)
    at emitTwo (events.js:125:13)
    at Request.emit (events.js:213:7)
    at Request.<anonymous> (/home/dreignier/cgstats/node_modules/request/request.js:1063:14)
    at emitOne (events.js:120:20)
    at Request.emit (events.js:210:7)
    at IncomingMessage.<anonymous> (/home/dreignier/cgstats/node_modules/request/request.js:1009:12)
    at emitNone (events.js:110:20)
    at IncomingMessage.emit (events.js:207:7)

The fast solution is to protect the code of course.
