tests: Speed up p2ps_connect_adv_go_persistent

Stop the pending P2P_LISTEN operation priot to issuing P2P_GROUP_ADD to
start a GO. This avoids excessively long wait for the previous Listen
step to complete before being able to start the GO. This makes
p2ps_connect_adv_go_persistent take significantly less time.
