When trials=0 (or any value <= n_initial), both RL and supervised
hyperopt binaries now auto-bump to n_initial+1 instead of bailing.
Previously the RL binary bumped to 5 which equalled n_initial=5,
triggering "trials must be greater than n_initial" error. The
supervised binary lacked the bump entirely and just crashed.
