Subject: [PATCH] Backport PR #4035: Fixed custom jinja2 templates being ignored when setting template_path

IPython/html/notebookapp.py was ignoring user specified templates by setting the jinja2 environment to the default template directory before updating template_path.  This fix allows a user defined template_path to propagate to the jinja2 environment.
