    CamelObject: Suppress state file warnings for old IMAP accounts.
    
    CamelImapFolder had a persistent "check-folder" property whose value was
    recorded in Camel's binary state files under tag 0x2500.  This property
    is not present in CamelIMAPXFolder, but we may still be reading the tag
    for accounts that were migrated from IMAP to IMAPX.  Check for that tag
    value while reading state files and suppress the runtime warning.
