I am trying to set and retrieve a value from the [NSUserDefaults standardUserDefaults] using UIAutomation javascript API.

The correct value is returned, but an error is thrown.

This is causing my JavaScript tests to fail.

Steps to Reproduce:

1. in Instruments 6.0, open a new Automation template
2. target an application that is running on an iOS 8 device
3. enter the following script:

```
var target = UIATarget.localTarget();

target.frontMostApp().setPreferencesValueForKey("value", "com.my.key")

var myValue  = target.frontMostApp().preferencesValueForKey("com.my.key")
UIALogger.logPass("myValue: ".concat(myValue));
```

4. run

Expected Results:
To see no exception or error thrown.

Actual Results:
```
pegasi com.apple.xpc.launchd[1] (com.apple.xpc.launchd.domain.system) <Error>: Caller not allowed to perform action: ScriptAgent.170, action = sandboxed lookup, code = 1: Operation not permitted, uid = 501, euid = 501, gid = 501, egid = 501, asid = 0
