Should be updated to work with newer jupyter

[JJK96]

The current version does not start. I got jupyter to start by changing

super(NotebookApp, self).start() to super().start(), however, then I ran into the following exception:

I think this is because the way the KernelManager is implemented no longer fits with how the KernelManager currently works in jupyter. I think a migration should be done following https://jupyter-client.readthedocs.io/en/stable/provisioning.html

Tested with: Python 3.7 Cutter 2.1.0
