  imapc: Don't use fetch-fix-broken-mails for OK and NO [SERVERBUG] FETCH replies

Hopefully no servers are actually returning OK without returning a FETCH
reply. If they are, maybe we need another workaround..

In any case Yahoo IMAP sometimes loses state and starts returning OK without
FETCH replies to all UID FETCH requests (and BADs to FETCHes). It also may
return NO [UNAVAILABLE] for both permanent and temporary FETCH failures, so
we can't do anything with that.

I added NO [SERVERBUG] because that's what Dovecot responds to temporary
failures. I'm not sure how useful that check is though.
