Description

Previously, 'Everyone' role wasn't included in export file because it doesn't exist in database, and the only roles that were exported were the roles from the db. I've added a code that forcefully adds 'Everyone' role to an array of roles when exporting, but doesn't add it to the 'roles' object. That way it is not added to the database when the project template gets imported, but at the same time the server can convert 'everyone' role to the ID and back.
