Remove dependency on DOM in CommonMobileModule

[viktor-podzigun]

Since we have to substitute references to react-native modules with corresponding mocks during test, we have used custom webpack config for it: sc-react-native-mocks.webpack.config.js which also required requireJsDomEnv in Test := true.

Apparently, there is a better way to mock modules on Node.js platform, by using:

• module-alias for JS modules
• and require.extensions[...] for mocking file resources
