Read a photo's real extension through a lazy proxy

member.getAvatar() returns a proxy of the base Avatar type, so instanceof AvatarPhoto was false and every photo was addressed as .png. A .jpg upload then 404'd, and the public officer card (loan application, member-pinned web chat) showed initials for a member who has a photo. Unproxy before reading the extension.
