Ensure using a Kubernetes provider with an incompatible resource doesn't panic

[stack72]

Fixes: pulumi/pulumi#3224

With the following code:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
import * as k8s from "@pulumi/kubernetes";

const wrongProvider = new k8s.Provider("wrong-provider")

const x = new aws.s3.Bucket("test", {}, {
    provider: wrongProvider,
})

Before:
