winston-logsene exception problem

Description.txt

If you throw an exception, winston-logsene isn't sending the log.

Take the example below. I went into logsene-js to add some logs for context, which are noted below.

Then run `LOGSENE_TOKEN=xxxxxxxxxx node test.js` to see the result.

It works fine with a short-running process (i.e. when `q()` is commented out). However, if you throw an exception to end the process, LogseneJS doesn't send it.

logsene-js..index.js

/**
 * Sending log entry  to LOGSENE - this function is triggered every 100 log message or 30 seconds.
 * @callback {function} optional callback function
 */
Logsene.prototype.send = function (callback) {
	process.stdout.write( 'Entering Logsene.prototype.send' );
  var self = this
  var count = this.logCount
  this.logCount = 0
  var options = {
    url: this.url,
    logCount: count,
    headers: {
      'User-Agent': 'logsene-js',
      'Content-Type': 'application/json',
      'Connection': 'Close',
      'x-logsene-origin': this.xLogseneOrigin || xLogseneOrigin
    },
    body: this.bulkReq.getContents(),
    agent: self.httpAgent,
    method: 'POST'
  }
  process.stdout.write('Body:');
  process.stdout.write( '\n\n' + options.body.toString() + '\n\n' );
  this.bulkReq = null
  this.bulkReq = new streamBuffers.WritableStreamBuffer({
    initialSize: initialBufferSize,
    incrementAmount: incrementBuffer
  })
  if (options.body === false) {
    return
  }
  process.stdout.write( 'Line before `var req = request.post(options, function( err, res ) {`' );
  var req = request.post(options, function (err, res) {
  	process.stdout.write( 'err = ' );
  	process.stderr.write( JSON.stringify( err ) );

    if (err || (res && res.statusCode > 399)) {

test.js

	      humanReadableUnhandledException: true
		}),
	]

logger.add (logsene, {
	token: process.env.LOGSENE_TOKEN, 
	type: 'test_logs',
	level: 'debug',
	handleException: true,
	humanReadableUnhandledException: true

logger.error( 'LOG IN TEST.JS' );

function a() { someUndefinedFunction(); }

console.log( new Date().toISOString() );

// *ONLY* If you comment q() out will the logs will send to Logsene
q();
