Yes, the tests pass after removing the code.

I can see from your and Ihor's response that my suggestion is
wrongheaded. 

After looking more carefully at ob-core, I am not sure how I could write
a test for the prep-session code, though. The comment and docstring in
ob-template.el does not help me, I am afraid. And the existing
session-related tests do not touch the prep-session code.

I'll poke around in other ob-*.el code and see if I can figure it out.
