fix(remote): name the machine, not its profile UUID, when a reconnect fails

A reconnect labelled its target with RemoteTarget's Display, which spells a
Profile target as the config UUID behind it. The banner's own half of the
sentence resolves the name through the live config, so one line said both
'Reconnecting to java-box' and 'could not reach 51d32f65-...'. Use
target_label, which #485 added for exactly this.
