This makes MerkleIntegritySourceStream match the new behavior of
draft-thomson-http-mice-03 [1], where the encoding of an empty payload
does not have the 8-byte record size.

Also, after this patch the final record must not be empty. Empty final
records were allowed because http-mice-02 couldn't represent the empty
payload otherwise.
