When an alias cannot be found for an `Author` the DID can be repeated eg.

To prevent this we output one of four cases:
* `(<alias>, (you))` -- the `Author` is the local peer and has an alias
* `(<did>, (you))` -- the `Author` is the local peer and has no alias
* `(<alias>, <did>)` -- the `Author` is another peer and has an alias
* `(<blank>, <did>)` -- the `Author` is another peer and has no alias
Notably, we output a blank `Label` when no alias was found.
