mb2q: Handle notmuch message ordering correctly

Notmuch provides the messages in a thread in reverse order, except for the
message which is the first one in a thread. This causes the patch ordering
in the resulting patch queue to be reverse.

Insert the mails into the list after thread starting message instead of
queueing them at the end.
