The remaining refactors are in a single patch.  I was also able to resolve the issue I had with inserting the test name for the session (the "yes" string in `test-ob-shell/session').

Because I often program in Python where double quoted strings typically don't span lines.  One of the original tests had the string "#+BEGIN_SRC sh :results list\necho 1\necho 2\necho 3\n#+END_SRC" in it (that is, used newline characters instead of inserting new lines), so my brain assumed strings Emacs Lisp behaved similarly to Python.  Silly brain :)  Thanks for continuing to follow up on that.

I've updated the patches to use bare strings.

If this set of patches look good, I can push them to main.

* testing/lisp/test-ob-shell.el
(test-ob-shell/dont-error-on-empty-results): Explicitly test handling
of empty results.
(test-ob-shell/dont-error-on-babel-error): Explicitly test handling of
Babel errors.  On pass, remove buffers created during test.

Original test conflated empty results (a valid Babel return) and Babel
errors.
