Stop bot cleanly when all routes are disabled

When every run has been auto-disabled there are no routes left to run, so save a
session report and shut down via safe_exit() instead of calling restart_or_exit
(which would needlessly restart D2R into empty games when restart_d2r_when_stuck
is enabled).
