Currently, If you are a Confluence administrator and a user has restricted a page to edit just for himself, the EDIT button still appears in the page, but if the administrator clicks on it and save the page, he'll receive a Not Permitted message and if he clicks on Close, he's not redirected to the view mode.

Steps to reproduce:

1. Create a 'test' user.
2. Create a page with the 'test' user.
3. With the Confluence admin account, go to that created page.
4. Click on Edit and then in Save.

Current Behavior:
You will receive a Not permitted message.

If you click on Close instead of Save, the page will not be refreshed. You'll see just a blank page.

Expected Behaviour:
You are able to save the page or Confluence admin will not be able to see the Edit button since the page is restricted.
