Bug

**What is the current behavior?**

I've narrowed it down to this:

https://codesandbox.io/s/usetransition-useeffect-dependency-issue-2olmx

Basically, what I *think* is important is:

1. There's a state change resulting in the useEffect being called
2. The useEffect callback starts a transition
3. The transition callback sets state
4. The set state results in a render which suspends

If these are all the case, then including the `startTransition` function in the dependency array will trigger an infinite loop. In the codesandbox I have a safety in place so your browser doesn't fall over.

**What is the expected behavior?**

The `startTransition` function should be consistent between renders.

I've observed that if you do not inline the config to `useTransition` then this is not a problem. I know that the docs recommend keeping this config consistent, but if this is desirable behavior, then maybe a warning about this particular situation in the docs would be useful. I expect that inlining the config will be pretty natural for people.

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**

- react@0.0.0-experimental-f6b8d31a7
- react-dom@0.0.0-experimental-f6b8d31a7
