Merge createActorContext options with Provider options

[davidkpiano]

Options in createActorContext are now properly merged with provider options. Previously, provider options replaced the actor options.

const { inspect } = createBrowserInspector();

const SomeContext = createActorContext(someMachine, { inspect });

// ...
// Options are now merged:
// { inspect: inspect, input: 10 }
<SomeContext.Provider options={{ input: 10 }}>
  {/* ... */}
</SomeContext.Provider>;

This test doesn't check that those options here were used - if the test is meant to check the merging behavior then we should have assertions validating that both of those are preserved somehow.

Improved the test to check that count: 10

It's already testing the top-level option by reading the events array
