Restore brings a Tty bash pane back running bash

A dogfood agent's `Tty bash` pane came back from Restore running fish: the
dump kept its directory but not the shell it was opened on. The dump's
terminal record now carries that shell (empty for the configured one, as
older dumps read), and Restore starts it again.
