Fix own profile error

Problem: A `null` relationship represents when it's your profile, which
isn't very intuitive. It causes an error when we try to check for the
`blocking` and `following` properties, which don't exist on `null`.

Solution: Instead of `null`, set a `me` property to tell whether this
relationship is our own profile.
