patch: ob-screen: don't change user-specified session name [9.3.7 (9.3.7-12-g5d6868-elpaplus @ /home/kdm/.emacs.d/elpa/org-plus-contrib-20200706/)]

[Ken Mankoff]

ob-screen prepends "org-babel-session-" to the user-specific screen name for 
some reason. I suggest this is not necessary nor optimal. One of the key points 
of 'screen' is that you can detach and attach from elsewhere. The name of the 
session is an important part of this process, and changing the user-chosen name 
complicates this. I note that in the other babel :session names I use (shell, 
Python, jupyter-python, etc.) the :session name is not modified.

  -k.
