py-ipython: updated to 6.3.1

IPython 6.3.1

This is a bugfix release to switch the default completions back to IPython's own \ 
completion machinery. We discovered some problems with the completions from \ 
Jedi, including completing column names on pandas data frames.

You can switch the completions source with the config option \ 
:configtrait:Completer.use_jedi.
