fix: Match first route for multiple matches in route list

[avonder]

If there's a wildcard path after a predefined path, e.g.:

limiter = Limiter(key_func=get_remote_address, default_limits=["1/second"])
app.state.limiter = limiter

@app.get("/a/")
@limiter.exempt
async def a():
    return "a"

@app.get("/{p}/")
async def path(p: str):
    return p

• exemption checks for first route match the second route.
