Allow implementing `sim.Resource` without an `onStop` method

[eladb]

Use Case

I want to be able to define a sim.Resource without a stopping method:

let resource = new sim.Resource(inflight (ctx) => {
  log("initializing...");
  ctx.resolveToken("foo", "bar");
});

let foo = resource.createToken("foo");

Proposed Solution

The factory closure that sim.Resource should not require a return value. If none is provided, then it should behave as if there's simply no onStop method.
