    [Camel] Freeze/thaw also subfolders of vFolders
    
    The problem with not freezing/thawing subfolders of vFolders exhibited
    in operations with multiple messages at once, like when deleting
    junk messages in a virtual Junk folder, the subfolders notified about
    each single message info change, causing performance issues.
