Comment 2 for bug 1744656

The code looked like a merge gone awry. There were at least two competing strategies on how to handle the aliases list, and they weren't getting along well.

I fixed the two bugs, and normalised the alias list. It now displays only the aliases (not the name of the root), and states what it is displaying at the top when the edited part is an alias. This brings the aliases list in line with the user model (where they're presented as aliases *of* the root, not a collection *including* the root).
