If skinny metadata is enabled and our first tree search fails to find a skinny extent item, we may repeat a tree search for a "fat" extent item (if the previous item in the leaf is not the "fat" extent we're looking for). However we were not setting the new key's objectid to the right value, as we previously used the same key variable to peek at the previous item in the leaf, which has a different objectid. So just set the right objectid to avoid modifying/deleting a wrong item if we repeat the tree search.
