[BPK-1754] Upgrade React Native to 0.57.3

[shaundon]

• Upgraded RN based on this guide.
• Changed Storybook command based on this issue.

Notes

We got Jest to run with the following things:

• Change .babelrc to babel.config.js (weird I know).
• Add @babel/core and babel-core and babel-jest to deps, based on the RN upgrade guide.
• Added Jest as a dependency in native. This isn't desirable long term as it diverges from the version of Jest used in the root. However I think this is better for now to keep this PR small. After this I plan to do another PR to upgrade Jest for web, then I can remove Jest from native.
• Upgrade React to 16.6. I wanted to avoid this but it's unavoidable, the tests won't work without it. It's specified in the upgrade guide here: https://github.com/react-native-community/react-native-releases/blob/master/CHANGELOG.md#0573.
• I had to add jest-cli to deps to get rid of environment.dispose is not a function errors. How is this even a thing I really don't know

As mandated here: https://github.com/react-native-community/react-native-releases/blob/master/CHANGELOG.md#updating-to-this-version

This update is because I did pod update to bump RN. I presume the other changes are ok though, seems to work fine.

Storybook used to run the RN packager for us but their usage doesn't work with the new RN (see storybookjs/storybook#4179).

So, now we run the packager ourselves. $PWD/.. is because Watchman won't accept a relative path (i.e. ..), so this was my hack workaround.

[shaundon]

• Updated Storybook to match the version in the root package.json. We should keep these in sync.
• Updated React as mandated in RN upgrade guide: https://github.com/react-native-community/react-native-releases/blob/master/CHANGELOG.md#updating-to-this-version

@shaundon just by comparing our package.json and yours, I can see few differences:

• you need both "@babel/core": "^7.0.0" and "babel-core": "7.0.0-bridge.0"
• "metro-react-native-babel-preset": "^0.45.6"
• "jest": "23.6.0"

In jest config, we have

    "transform": {
      "^.+\\.jsx?$": "<rootDir>/node_modules/react-native/jest/preprocessor.js"
    },

.babelrc:

{
  "plugins": ["codegen"]
}

skyscanner-app/react-native/scripts/metro.config.js

const path = require('path');

module.exports = {
  transformer: {
    babelTransformerPath: require.resolve('./transformer'), // NOTE: we use react-native-obfuscating-transformer
  },
  projectRoot: path.resolve(__dirname, '..'),
};
