    [IMAPx] Set cache expiration for one week when not sync-for-offline
    
    When the folder, or the account, is not set to be synced for offline,
    set the cache expiration for one week, thus the local cache doesn't
    blow indefinitely when the user doesn't want offline access to
    downloaded messages.
