Steps to Reproduce

-Create an Editor user
-Login with the Editor user
-Edit eZ Platform Home page

From now on, we have two scenarios
scenario1 - click "save" button
-Click "Save button" - We can see that we have an "ok" notification

scenario2 - click "save" button only after clicking "publish" button
-click "publish" button - we have an error notification
-click "save" button - again we have an error notification (in oposite to Scenario1, that returned an "ok" notification)

Due EZP-26550, it was not possible to verify if this happens in released versions of eZ Platform
