After re-opening TBird, some IMAP folders do not have a total number of mails
listed. When clicking these folders, TBird retrieves the mail headers from the
IMAP server, just as if that would be the first time it would retrieve headers
of that folder.

Reproducible: Sometimes
Steps to Reproduce:
1. Close TBird.
2. Re-open it.
3. Click on an IMAP folder that shows a total number of 'nothing'.

Actual Results:  
TBird retrieved the mail headers for the folders once again.

Expected Results:  
It should only retrieve new mail headers.

Just to confirm this behavior - 0.5 did not have this problem.

Our business makes extensive use of shared IMAP folders (Cyrus IMAPD) and in 
0.7.x, after closing and re-opening Thunderbird, the mailbox is 'brand new' in 
the sense that there are no stored headers, and the entire mailbox must be re-
indexed. On large mailboxes (even with a very fast Xeon mail server), this can 
take 20+ seconds.

This is on a local network too - just takes a while to download 5000+ headers.

This problem is a show-stopper for us, and we must continue to use 0.5 as a
