Issue DM-3670: obs_test needs to override map_camera and std_camera
The Butler can't get a camera unless the map_camera and std_camera are defined correctly. In most cases the camera can be built by the map_camera method. In the case of obs_test, the camera is built in the constructor of the Mapper, so std_camera should just return the camera attribute.
