"Unexpected values found in emails" when upgrading to 8.0

Hello,

When doing the upgrade from 7.9.4 to 8.0, I had this warning during the healthcheck :

82. Unexpected values found in emails
Invalid status and type for emails: status=read, type=out Learn more...

83. Unexpected values found in emails
Invalid status and type for emails: status=read, type=archived Learn more...

84. Unexpected values found in emails
Invalid status and type for emails: status=read, type=draft Learn more...

The explanation link is broken : http://support.sugarcrm.com/Knowledge_Base/Installation_Upgrade/Troubleshooting_Health_Check_Output/Health_Check_Error_Invalid_Status_and_Type_for_Emails/

I did the update anyway and now all my existing emails have a status of "Archived" instead of Sent/Read/Unread. I sent a new e-mail and it was set to "Archived" instead of Sent.

I saw that in the database, the table "emails" has a new field "state". So it seems that the interface display the state instead of the status of the e-mail because the e-mail has the state "sent" in the database;
