Devices: fixes from review round 20

- A jump host's own "Authenticated to" line no longer counts as the headset's,
  and a master that logs in but doesn't start lets the next address be tried.
- Devices tab changes refresh through the ordered list load, so a late answer
  can't undo a newer selection.
- A probe's time out starts after the name lookup: macOS can take 5 s to look
  up a .local name (found on the real Frame once its USB link went away).
- An attempt's ending is published from a method, not a return in finally.
