fix(install): raise the install tab only when there is something to doHEADmaster

The recap was handed to the steps window on every run, so the file always
existed. Any later poke, such as udt-grub or udt-homepage starting from a
login's wallpaper restore, reopened the window on an old summary with
nothing to act on. Keep the tab only when install.sh failed or printed a
command; clear it otherwise.
