Photos permissions not working on IOS 7

[smarongiu]

Bug

Version Number of Plugin: 1.1.7
Device Tested On: iPhone 4 (with iOS 7.1.1 and 7.1.2)
Simulator Tested On: -

Expected Behavior

If permission was granted, PermissionStatus result should be "Granted", otherwise it should ask for permission.

Actual Behavior

PermissionStatus is "Unknow" => no popup asking for permission, application flow is stalled on the request task.

Steps to reproduce the Behavior

Build&Run PermissionSample app on a device with iOS 7 (without granted permissions for the app), click on "Photos"
=> popup : Result "Unknow", click on "Ok"
=> app is stalled, no popup to ask for permissions
