CBD-87: don't restore NRU info, only seq_no info
CBD-87: don't restore NRU info, only seq_no info

Even though we backup the full meta field (seqNo + NRU) from the TAP
stream to be future ready, we only want to restore the 64-bit seqNo as
the current 2.0 XXX-WITH-META commands don't support the NRU field.
