* If a node claims to fail a transfer due to piece not found, remove that node from the pointer, delete the transfer queue item.
* If the pointer is piece hash verified, penalize the node. Otherwise, do not penalize the node.
* check duplicate node id before update pointer
* add test for transfer failure when pointer already contain the receiving node id
* check exiting and receiving nod are still in the pointer
* check node id only exists once in a pointer
* return error if the existing node doesn't match with the piece info in the pointer
* try to recreate the issue on jenkins
* should not remove exiting node piece in test
* Update satellite/gracefulexit/endpoint.go
