A user with admin type and "Create and edit dashboards" permissions can't save a cloned public dashboard. (but can clone and save an owned dashboard)

Steps to reproduce:

1. Login as user with  "Create and edit dashboards" permission (not superadmin)
2. Press "clone" on public dashboard's actions menu
3. Choose a new name and click "Apply"
4. Click the "Save changes" button

Result:
Got error:

"Access denied

• You are logged in as "test_new". You have no permissions to access this page.
• If you think this message is wrong, please consult your administrators about getting the necessary permissions.

  Expected:
  Saving the new (cloned) dashboard
