    app: fix child offsets of a pasted layer group
    
    Use gimp_item_translate() instead of gimp_item_set_offset() to set
    a pasted item's position, so that the offsets of pasted layer group
    children are updated correctly.  Otherwise, only the group itself
    moves, while its children remain positioned relative to the top-left
    corner of the image.
