[geary/mjog/790-email-flag-interleaving: 7/7] Geary.Imap.FolderSession: Use the SILENT option when sending IMAP STORE

[Michael Gratton <mjog src gnome org>]

commit 831cd0f476b7d6059d4cafb192517f0ddc2fe8ef

    Geary.Imap.FolderSession: Use the SILENT option when sending IMAP STORE
    
    Not having the server echo the command back saves a useless round-trip,
    and prevents undesirable interleaving when executing multiple STORE
    commands in quick succession.'
    
    Fixes #790
