[TIMOB-26551] iOS: "Cannot read property 'code' of undefined" error thrown if log server connection times out

Description

When checking the log server connection in the iOS build if the check times out then the following error is thrown. I'm unsure as to the actual reasons for why I ran into this, but you can easily reproduce by reducing the logserver wait time

/Users/eharris/Library/Application Support/Titanium/mobilesdk/osx/8.0.0.v20181109074008/iphone/cli/commands/_build.js:2506
                                if (error.code === 'ENOTFOUND') {
              ^
TypeError: Cannot read property 'code' of undefined
    at Socket.die (/Users/eharris/Library/Application Support/Titanium/mobilesdk/osx/8.0.0.v20181109074008/iphone/cli/commands/_build.js:2506:15)

Steps to reproduce

1. Reduce the logserver wait time using appc ti config ios.logServerTestTimeout 1 2. Build an iOS app for simulator or device

Actual

Error thrown like the above

Expected

Error thrown should inform the user the real reason it errored
