Hide Cron messages when appropriate

Hi –

We have opted to purposefully turn off the normal WP Cron trigger that runs on every page load by adding define( 'DISABLE_WP_CRON', true ); to wp-config and run it via an actual server level crontab event that runs once per minute.

Using this setup we’re constantly getting the error “WP Offload SES — WP Cron does not appear to be working correctly. Please see our cron setup doc for more details.”

Would be great to have an option to hide this message if we’ve confirmed that our server-level cron is successfully sending emails out… or even better yet – improve the test that determines if this message appears to be able to detect if a server-level cron is running successfully or not.
