upas/fs: fix sync condition

Browse source 
we used to check for mb->d->name != nil before stating, to avoid
stating pop3/imap mailboxes who don't really have a local file,
but this breaks when the md->d is reconstructed (faked) from
the index! resulting in the mailbox stop being refreshed.

the solution is to not have mb->d == nil for imap/pop mailoxes.
