Fixed a problem with sqimap_unseen_messages where some versions of UW

Imap will send 2 lines of response on a STATUS mailbox (UNSEEN) when
the last EXAMINE was on the same mailbox.  This kept the INBOX from
displaying the number of unread messages.  This seems like valid behaviour
to me, but UW IMAP doesn't like it depending on how it's been compiled.
