Fixes the following issue: #230

Need to fix how mapping is displayed in export jobs view mode.
I think this class should not exists and is not really needed.
getAttributes(array $criterias) and getImageAttributeChoice() should be added to AttributeManager class in pim-community-dev
Same for getRepository method and you have to remove the dirty instanciation ^^

For now, you can just remove the repository instanciation but add deprecated tags inside the two others methods.
