Environment

How do you use Sentry?
Sentry SaaS (sentry.io)

Which SDK and version?
sentry-sdk 1.1.0 (pypi)

Steps to Reproduce

Using the Quart framework, and the ASGI integration provided in the SDK (docs), as well as following the Quart middleware documentation, quart_app.asgi_app is treated as an ASGI 2 app while it should be treated as an ASGI 3 app.

Expected Result

The SDK should work, providing request context for errors.

Actual Result

It seems like integrations/asgi.py#L53 is causing quart_app.asgi_app to report as an ASGI 2 application, erroring out with _run_asgi2() takes 2 positional arguments but 4 were given.

Additionally, creating a new variable based on quart_app, instead of quart_app.asgi_app (sentry_app = SentryAsgiMiddleware(quart_app) and serving that seems to work.

Quoting @pgjones from the Quart Gitter

Ideally it should work with the app.asgi_app, which I think (if it works with app) is the crucial part to put in the bug report to sentry
