BUG/MAJOR: contrib/spoa-server: Fix unhandled python call leading to memory leak

The result from spoa evaluation of the user provided python code is
never passed back to the main spoa process nor freed.
Same for the keyword list passed.
This results into the elements never freed by Python as reference count
never goes down.
https://docs.python.org/3/extending/extending.html#reference-counting-in-python

This patch must be backported as far as 2.0.
