admin cannot modify/delete campaign in specific case

[stevenolen]

just a note.

An admin has no control over a campaign from the frontend when they are 1)not an author and 2)the campaign is attached to no class.

Current workaround is to update campaign to have admin as author via curl (or easypost):
curl -d 'client=curl&auth_token=token_here&campaign_urn=campaign:urn:here&user_role_list_add=admin.user;author' https://ohmageserver/app/campaign/update
