REGRESSION Cannot launch iOS 7.0.3 Simulators with instrument Xcode 6
Improved cukes for testing reset app sandbox

We were using the reset of NSUserDefaults as a proxy for success.

This is broken on Xcode 6 w/ command line instruments.  The new
strategy drops files into the app sandbox and queries for there
existance before and after resetting the sandbox.
Spec should always fail for Xcode > 6.0

It is not clear how we can test reset_app_sandbox for Xcode 6.

For now we just fail to remind devs that this specs need review.

Tests fail locally, but CI uses Xcode 5.1.so tests are stable.
