Philipp von Weitershausen d7c8b4478b Make InteractionManager.runAfterInteractions() return a Promise
Summary: In accordance with the unwritten rule that any API that takes a callback should also return a promise, I've changed `InteractionManager.runAfterInteractions()` to do just that.

```js
  InteractionManager.runAfterInteractions(() => {
    ...
  });
```
can become
```js
  InteractionManager.runAfterInteractions().then(() => {
    ...
  });
```
(but doesn't have to). Most importantly, though, this change enables code like
```js
  doSomeUIStuff();
  await InteractionManager.runAfterInteractions();
  doSomeNonUIStuff();
```
which is nice.

Note: Because returning a `Promise` means the callback argument is now optional, the behaviour of the API is slightly changed, though not in a backwards-incompatible way (unless a consumer is in some way relying on the exception, but that would be insane).
