[nextage_calibration] Checkerboard does not appear on melodic

[pazeshun]

When I tried gazebo_kinect_checkerboard_chest.launch on melodic, I faced the following error:

$ roslaunch nextage_calibration gazebo_kinect_checkerboard_chest.launch

This is because spawn_model parameter differs between kinetic and melodic.
On kinetic,

$ rosrun gazebo_ros spawn_model --help
SpawnModel script started
Commands:
...
    -wait - optional: !!!Experimental!!! wait for model to exist

On melodic,

$ rosrun gazebo_ros spawn_model --help
...
  -wait MODEL_NAME      !!!Experimental!!! wait for model to exist
