Summary:
Running instruments from the command line without a specific device selected via the `-w` flag results in the error "Automation is not available for this type of application"

Steps to Reproduce:
1. Install Xcode/CLI tools
2. Run a basic instruments CLI command with an iOS8 test application/script:

/Applications/Xcode6-Beta.app/Contents/Developer/usr/bin/instruments -t /Applications/Xcode6-beta.app/Contents/Applications/Instruments.app/Contents/PlugIns/AutomationInstrument.xrplugin/Contents/Resources/Automation.tracetemplate /path/to/my.app -e UIASCRIPT /path/to/my/test.js -e UIARESULTSPATH /tmp

Expected Results:
I expect the simulator to launch with the default device and run my app and test script, the way it does in Instruments 5

Actual Results:
We see this error:

2014-06-18 18:17:13 +0000 Fail: Exception: Automation is not available for this type of application.

Verbose mode gives us some more information:

Notes:
I also can't get an automation trace to successfully start from Instruments.app. It will start the app (so it gets further than instruments CLI), but even a simple 1-line UIAutomation script will immediately fail with no information given as to the reason
