srcset images are not generated <v:media.image />

[muehle28]

When the image gets preprocessed the srcset images are not generated. This happens if the crop feature is used or the quality of the image is changed. There is a problem with the processing of processed images. If treatIdAsReference=TRUE the srcset images are generated from the original image. Therefore the crop and ratio informations are needed.

I generated a pull request to solve the problem when treatIdAsReference=TRUE
#1096

When treatIdAsReference=FALSE the generation of the images still fails.
