Fixes

@jlipps I've commented this out, when I leave it on the following sequence of tests fails because this.pageIdKey is `NaN`:
```
DEVICE=ios71 mocha -g '@skip-ios7|@skip-ios-all' -i --recursive test/functional/ios/safari/webview/window-title-specs.js test/functional/ios/safari/windows-frame-specs.js
```
