1. Update the test app
If I understand correctly, the debug toolbar will only be enabled if `app.debug` is `True`. So I added the `DEBUG=True` to the test app.
Related code: 2b8bf9cc44/src/flask_debugtoolbar/__init__.py (L114)
2. Update the `src/flask_debugtoolbar/__init__.py`
Fix the two if statements to prevent the following errors:
```
> if 'gzip' in response.headers.get('Content-Encoding'):
E TypeError: argument of type 'NoneType' is not iterable
```
Since the `response.headers.get('Content-Encoding')` could be None.
With this PR, all the tests will be passed. The failed style checker will be fixed in #219
Flask Debug-toolbar
===================
This is a port of the excellent `django-debug-toolbar <https://github.com/jazzband/django-debug-toolbar>`_
for Flask applications.

:target: https://github.com/pallets-eco/flask-debugtoolbar/actions
Installation
------------
Installing is simple with pip::
$ pip install flask-debugtoolbar
Usage
-----
Setting up the debug toolbar is simple::
from flask import Flask
from flask_debugtoolbar import DebugToolbarExtension
app = Flask(__name__)
# the toolbar is only enabled in debug mode:
app.debug = True
# set a 'SECRET_KEY' to enable the Flask session cookies
app.config['SECRET_KEY'] = '<replace with a secret key>'
toolbar = DebugToolbarExtension(app)
The toolbar will automatically be injected into Jinja templates when debug mode is on.
In production, setting ``app.debug = False`` will disable the toolbar.
See the `documentation`_ for more information.
