Counter values don't get recalculated anymore after the whole list is loaded.

[bedhub]

1. Have wrong folder counter
2. Load all mails of that counter
3. Error -> Counter is not updated

Expect: Folder counter should be synchronized.

Hint:

• it may be possible to override counter values with the admin client to get to the broken state
• check if the count gets recalculated at all at the intended time
• try breaking something in the client to get to an invalid count
