Packager notes:
Downgrading to 0.17.2 because version 0.18.0 breaks spyder3.
Also python3-jedi version 0.18.0 requires newer version of python-parso which have dropped python2 support.
At this moment we can't drop python2 module of python-parso because it will break many other packages like:
cython, numpy, printrun, mypaint, displaycal etc.
Reference task T9866 for tests.
