An exception raised within an asgi lifespan context manager would result in a "lifespan.startup.failed" message being sent after we've already sent a "lifespan.startup.complete" message. This would cause uvicorn to raise a `STATE_TRANSITION_ERROR` assertion error due to their [check for that condition][1]. This PR modifies `ASGIRouter.lifespan()` so that it sends a shutdown failure message if we've already confirmed startup. This is consistent with [starlette's behavior][2] under the same conditions.
