CB-7259: Set default value of correctOrientation to true in camera plugin

Jira Ticket : CB-7259
https://issues.apache.org/jira/browse/CB-7259

Platform: iOS
Plugin: org.apache.cordova.camera
Hardware: iphone 5

Issue:
Strange behavior when selecting photos from library with camera.getPicture and cameraOptions with sourceType of Camera.PictureSourceType.PHOTOLIBRARY. Some photos rotate in unintuitive ways.


Fix:
I found that defaulting correctOrientation to true in my cameraOptions argument fixed this problem.
