Issue with dressing test script in the phy-robo-care branch.

[rohanb2018]

Hello, there appears to be an issue with the templates/test_dressing.py script in the phy-robo-care branch of this repo. The observed behavior is that the cloth is on the rack, but the robot does not move. From debugging with @alkdischen's help, it seems like the issue is in the following line, which hangs:

env = RCareWorld(executable_file="Dressing/DressingPlayer.x86_64")

So there may be something wrong with that Unity executable file.

The problem has now been resolved, and the scene file has been re-uploaded to GitHub!
