[RSDK-4561] Remove unused check

[njooma]

When MovementSensor was still a subclass of Sensor, we had to exclude adding registering a Sensor subtype with the robot for every MovementSensor so as to not duplicate the available resources.

Now that MovementSensor is distinct from Sensor, we can remove that check

Seems like the only real change was the removal in client.py, and the other changes were formatting? If so, LGTM!
