    Geary.Imap.MinimalFolder: Update flag updater to use larger batch sizes
    
    Since with the `get_multiple_email_by_id` change in the last commit,
    he flag updater now accesses the remote directly and optimise the IMAP
    commands sent somewhat. As a result, larger batch sizes can reduce
    the number of bytes transmitted, and reduce the effects of network
    latency a bit as well.
