runserver_plus creates two pin codes for werkzeug debugger

Whenever I use runserver_plus to start a development server using the werkzeug debugger, it activates the debugger twice and prints out two pin codes. I expect there to be only one. Other than printing two pin codes in the terminal, the server runs perfectly as expected.

Steps to replicate:

# create a new empty virtualenv
pip install django ==1.9.2
pip install django-extensions==1.6.1
pip install werkzeug==0.11.3
django-admin.py startproject testproj
# Edit the testproj INSTALLED_APPS setting to include django_extensions
./manage.py runserver_plus

Output looks like this.

...
 * Debugger is active!
 * Debugger pin code: 140-764-085
 * Debugger is active!
 * Debugger pin code: 895-622-303

@kkroboth In addition, fixed the issue with --noreload @ 4d83167.

I was able to test the werkzeug repl with and without --noreload.

@tony There is a misplaced comma making a tuple for handler.

With reload

$ ./manage.py runserver_plus 

 * Running on http://127.0.0.1:8000/ (Press CTRL+C to quit)
 * Restarting with stat

Django version 1.9.2, using settings 'testproj.settings'
Development server is running at http://127.0.0.1:8000/
Using the Werkzeug debugger (http://werkzeug.pocoo.org/)
Quit the server with CONTROL-C.
 * Debugger is active!
 * Debugger pin code: 423-442-950

Without reload Works after removing comma.

$ ./manage.py runserver_plus --noreload

 * Running on http://127.0.0.1:8000/ (Press CTRL+C to quit)

The debuggers work in both instances, but the code is only shown after console is opened in browser if using –noreload.
