Checking mail overwrites custom status attributes

[humdinger]

This is beta2.

• Open a read email.
• Invoke "File | Close and | Set to..." and set some custom status, like "Later".
• Open a query for status=Later from the Find... panel.
• Check for new mail with the Deskbar replicant.
• Wait until the check has finished (watch send/received) of the ActivityMonitor)
• Check again for new mail.

--> watch how your "Later" returns to "Read". :(
