Description

Used to work with axum v0.6.12, but since I just updated to v0.6.15 the ServeDir service does not work anymore.

With this kind of code:

	let routes_static =
		Router::new().nest_service("/", get_service(ServeDir::new("./")));

	let routes_all = Router::new().fallback_service(routes_static);

	let addr = SocketAddr::from(([127, 0, 0, 1], 8080));
	axum::Server::bind(&addr)
		.serve(routes_all.into_make_service())
		.await
		.unwrap();

When doing a GET to a known path, like /src/main.rs

thread 'tokio-runtime-worker' panicked at 'assertion failed: matches!(extensions.remove :: < MatchedPath > (), None)', /Users/jeremychone/.cargo/registry/src/github.com-1ecc6299db9ec823/axum-0.6.15/src/extract/matched_path.rs:146:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Expected result: as in v0.6.12
