User that is not the Admin can restore pages deleted by admin

Steps to follow to reproduce:

• log in as admin
• create a page
• delete the page
• create a new user
• log in as the new user
• go to the page that has just been deleted by the Admin

Result: You can restore the page deleted by the Admin while logged in as a normal user.

Since the user did not create that page and doesn't have rights to delete it he shouldn't be able to restore it either.

Notes:

• This is particularly important for user profiles. A user that's not an admin cannot create/delete other users, so he shouldn't have the right to restore them either.
• If you go to the "Document Index", to the "Deleted Documents" tab you can restore all docs
