AttributeError: 'StreamResponse' object has no attribute 'body' exception occurs when serving static html

[rutsky]

Steps to reproduce:

1. Setup official demo: https://github.com/aio-libs/aiohttp_debugtoolbar/blob/master/demo/README.rst

2. Create empty HTML file in static files directory:

   $ touch demo/static/test.html

3. Start demo:

   $ python demo/demo.py

4. Open http://localhost:9000/static/test.html in browser.

Expected behavior: empty html is being rendered in the browser and no errors occurs.
Observed behavior: empty html is being rendered in the browser, but in the console following stack trace occurs:

$ python demo/demo.py

Thanks for so clean error report.
Toolbar should pass StreamResponse through gracefully.

Would you make a pull request?

I barely touched related code in my project and don't know this code at all, so I can't provide fix for it, sorry.

[asvetlov]

I'll fix it than
