searchidx: store the primary MID in doc data for NNTP

We can't rely on header order for Message-ID after all
since we fall back to existing MIDs if they exist and
are unseen.  This lets us use SearchMsg->mid to get the
MID we associated with the NNTP article number to ensure
all NNTP article lookups roundtrip correctly.
