    Further work around issues presenting windows under gnome-shell.
    
    Follow-up to Bug 776881 and commit e333794f, fixes Bug 794264.
    
    * src/client/application/geary-application.vala,
      src/client/composer/composer-container.vala: Use
      GLib.get_monotonic_time() instead of get_real_time() when calling
      Gtk.Window.present_with_time to avoid issues with mutter/gnome-shell
      alt-tabbing.
