Here it configures port but no master uri. It cannot connect to rosmaster on remote machine.

How about adding the env arguments following function?

If env arguments is existed, it is added in roslaunch_env .

I found the reason of this problem.
When app whose type is roslauch launched, terminal class in rocon_python_utill set the --port option. But if the port option is set, roslaunch does not reference ROS_MASTER_URI setting in environment variable.
If you check this phenomenon, you can use test rocon tools.
