jest snapshot serializer importing from 'dist' in version 0.7.2

[sidhu663]

The problem
I'm not 100% sure this is a bug but I think it probably is:
Given the following config (without using react-native-web babel plugin, using webpack 2):

// jest.config.js
{
  snapshotSerializers: ['enzyme-to-json/serializer', 'react-native-web/jest/serializer'],
  "transformIgnorePatterns": ["node_modules/(?!react-native-web)"],
  "moduleNameMapper": {
    "react-native": "<rootDir>/node_modules/react-native-web"
  },
}

Jest snapshots fail since the jest serializer is using StyleSheet from const { StyleSheet } = require('../dist');, whereas the components render using the ES6 StyleSheet built by webpack resulting in 2 different registries.

Yeah sounds right.

What I'm thinking of doing is removing the serializer and making StyleSheet.create the identity function when NODE_ENV==='test'. That will be simpler (and work for either cjs or esm) and retain the array of styles in the snapshot. Eventually can provide this as part of a jest preset like React Native's that does things like mock out View too.
