devel/ipython: actually unbreak autocompletion

Remove broader patch added earlier - it still doesn't completely
solve the problem.
Instead add tiny patch to fix runtime with jedi 0.18 and add missing
imports with second patch. Works just well with my tests.
Both patches should be removed after next ipython release.
