Behaviour for auto selecting new camera images is not complete

[roycornelissen]

When you navigate to the Grid view for a different collection than the Camera Roll and you take a new picture while AutoSelectCameraImages is YES, the new picture is not automatically selected.

I added some code to the GMAlbumsViewController in my port to make sure the photo is auto selected even if not in view. See roycornelissen/GMImagePicker.Xamarin@708d035
