I found out one interesting thing: unindexed tuple (that comes from amcheck scan) does not exist in heap page at the
momentof check fail. 
I've added ReadBuffer() in case of bloom_lacks_element() and ItemIdHasStorage() is false.
I understand that this description is a too vague, so I attached a patch for amcheck relaxing bt_index_check() so the
testwould pass.
