Summary:
This diff removes the `sinon` dependency from `metro` and `react-native-github`. It was only used in a handful of tests and having to learn and remember another mocking API just for these cases was not worth it IMO.
While doing the migration, most of the things that `sinon` provides can be done with `jest` in a very similar (and user friendly) way.
I've found, though, two small things that are more user friendly with `sinon`. I'm documenting them here because it may be worth adding them to jest:
With `sinon`:
```
stub.throws(new Error('foo'));
```
With `jest`:
```
mock.mockImplementation(() => {
throw new Error('foo');
});
```
Taking into account that `jest` has a `mockRejectedValue` method for mocks (to return a rejected promise) I don't see any reason why it does not have a `mockThrowError` method.
With `sinon`:
```
expect(mock1.calledBefore(mock2)).toBeTruthy();
```
With `jest`:
```
expect(mock1.mock.invocationCallOrder[0]).toBeLessThan(
mock2.mock.invocationCallOrder[0],
);
```
There's a community matcher that adds this matcher in `jest-extended`: https://github.com/jest-community/jest-extended#tohavebeencalledbefore, but we're not using `jest-extended` in `xplat/js`.
