Inbox desynchronised when modified externally

[nemesis]

The inbox (and possibly other folders) displays messages that don't actually exist when folder has been modified externally (e.g. mail downloaded by thick-client).

Steps to reproduce:

1. Login to roundcube instance
2. View an email
3. Logout
4. Download and delete all emails (e.g. using Thunderbird or Eudora)
5. Log back into roundcube
6. Click 'Check for new messages' icon.

Emails that do not exist in the inbox on the mailserver appear in the listing.
Double-clicking on the email does nothing.

I hazard a guess that it is because the messages still appear in the MySQL table.

Mail server: Courier 3.0.8 (3.0.8-4sarge4)

Mail client used: Eudora 6.2.1.2

Just to clarify -- I am assuming that new messages are recieved between Step #4 and Step #5.

Also, modify step #6 to:

6. View an email
7. Click the 'Back' green arrow, or the 'Inbox' icon on the left.

e-mail refresh has been fixed. Also when opening with multiple clients, tainting results like these can be expected
