Unable to continue task after exiting lift (#534)

Posted by @MrOCW:

Ending lift [lift_1] session for [TEMI/ROBOT-6]
Releasing lift [lift_1] for [TEMI/ROBOT-6]

Here are my logs for the fleet adapter.
After exiting lift at destination floor and returning True for is_command_completed, i still get spammed with
rmf_lift_msgs.msg.LiftRequest(lift_name='lift_1', request_time=builtin_interfaces.msg.Time(sec=0, nanosec=0), session_id='TEMI/ROBOT-6', request_type=0, destination_floor='', door_state=0)
and my robot does not proceed to the next waypoint. No command from RMF was given
