Indeed, something in Emacs is making incorrect assumptions.

The result here is

 "__PYTHON_EL_eval(\"print('a')\", \"/Users/mattias/emacs/asdf.py\")\r\na"

which is consistent with the test failure -- something in python-mode is having 
trouble parsing the reply. I traced `python-shell-output-filter`; see attached 
file.

This might be bug#25753 again (via a comment in etc/PROBLEMS). Even if no 
effort is made to fix the bug properly, we should make sure the test doesn't 
fail.
