pgcli.magic conn.session.engine.url raises AttributeError after breaking change upstream in ipython-sql

[tavisrudd]

This reference to session in pgcli.magic conn.session.engine.url raises an AttributeError for the current HEAD version of ipython-sql (after catherinedevlin/ipython-sql@9fbf83b). It can be changed to just conn.url.

However, it's probably worth moving off ipython-sql to https://github.com/ploomber/jupysql which is a maintained fork of it.
