Description
Currently we send the EOF to the fast store and the requester at the same time. The bytestream_server drops the get_part future as soon as it receives the EOF which means that the fast store doesn't get time to sync and populate.
This is resolved by only sending the EOF to the requestor in the fast_slow_store once all of the futures have completed. The alternative is to spawn for the fast store or to complete the get_part future in bytestream_server, but this seems like the least heavy weight solution which doesn't require thought by the user.
Fixes #478
