Jehan e72f5614da app: properly blink the right locked layer when pixels are locked. 
In particular, if painting on a layer whose parent's pixels are locked,
we were blinking an empty lock spot, which is confusing. Now
gimp_item_is_content_locked() will also return the proper item (when
relevant, i.e. when returning TRUE) which is locked. It may or may not
the same item as passed in (it may also be a parent item in particular).
