elm - genlist - fix leak if someone steals objects on unrealize

elm_genlist_item_all_contents_unset() can steal away the item content.
this is how you do a cache of your own objects... BUT this meant
genlist couldnt remove its hash entires... as it lost them. this fixes
that. leak fixed. (this affected evisum)
