How can I suppress this message for Webform version 7.x-4.10?
This is shown if you have the Show "Save draft" button option ticked in any webform and is hardcoded into the Webform form builder. If you want to override the message display the Disable Message module can help you here.


  Gives a site owner options to disable specific messages shown to end
  users. The core drupal message system as offered by drupal_set_message
  is an excellent way for modules to send out messages to the end users.
  However not all drupal site owners are keen to show all the messages
  sent out by drupal core and all modules to their users. This module
  gives site administrators a reasonably powerful way to filter out
  messages shown to the end users.
