Component used: Compose Navigation

Version used: 2.6.0-alpha06

Description: The app crashes on a deeplink if a composable destination has a navigation argument which is not String.

Code sample to reproduce:

        val navController = rememberNavController()
        NavHost(
            navController,
            startDestination = "a"
        ) {
            composable("a") {
                Column {
                    Text(
                        text = "navController.navigate()",
                        modifier = Modifier
                            .background(Color.LightGray)
                            .padding(24.dp)
                            .clickable {
                                navController.navigate("b/123")
                            })
                    Text(
                        text = "deeplink",
                        modifier = Modifier
                            .background(Color.Red)
                            .padding(24.dp)
                            .clickable {
                                val deepLinkIntent = Intent(
                                    Intent.ACTION_VIEW,
                                    "/456".toUri(),
                                    this@MainActivity,
                                    MainActivity::class.java
                                )
                                val deepLinkPendingIntent: PendingIntent? =
                                    TaskStackBuilder
                                        .create(this@MainActivity)
                                        .addNextIntentWithParentStack(deepLinkIntent)
                                        .getPendingIntent(
                                            0,
                                            PendingIntent.FLAG_UPDATE_CURRENT or PendingIntent.FLAG_IMMUTABLE
                                        )
                                deepLinkPendingIntent?.send()
                            })
                }
            }
            composable(
                "b/{id}",
                arguments = listOf(navArgument("id") { type = NavType.IntType }),
                deepLinks = listOf(navDeepLink {
                    action = Intent.ACTION_VIEW
                    uriPattern = "/{id}"
                })
            ) {
                Text("Id=${it.arguments?.getInt("id", -1)}")
            }
        }
    }

The first button with "b/123" route navigates successfully. The second that sends the deeplink with "b/456" route causes a crash.
