The tree's top row showed the placeholder name, since nothing ever read the
real one; take it from initserver, which ts3j now keeps.
There is only ever one top-level row, so its expand control bought nothing and
cost horizontal space in a narrow view. Drop it, ignore collapse requests on
the root, and tighten the per-level indent.
