Description

Running an iOS app on device from Ti CLI causes exception when quitting via CTRL-C.

/Users/chris/Library/Application Support/Titanium/mobilesdk/osx/6.1.0/node_modules/node-ios-device/ios-device.js:199
		if (emitter._events[udid].length <= 0) {
                           ^
TypeError: Cannot read property 'length' of undefined

    at emitOne (events.js:77:13)
    at EventEmitter.emit (events.js:169:7)

I also noticed that node-ios-device would sometimes blow up due to an uncaught exception:

To test, build an iOS app for device. Make sure the device is connected over both USB and Wifi. How do you know if you are connected via Wifi? I have no clue. Another way to test this is to just run node-ios-device's log test since the bug essentially has to do with starting the syslog service.
