fix(android): update templates & tests to fix RN v0.47.2 breaking change

[peggyrayzis]

What: Closing #30

Why: Breaking change in RN v.0.47.2

How:

• Check RN version from package.json
• Override createJSModules in Android & Kotlin templates for the package if version is below v0.47.2
• Take out createJSModules override if version is latest or above
• Updated readAndWriteFiles & parseFile functions to take a config option as second param
• Updated Jest tests

Thanks for pointing out that I needed to do the version check, @andrerfneves! Would you like to give this a review? 😀

Looks really good @peggyrayzis. The only thing I'd note is that this check if (rnVersion < "0.47.2") may not always return correctly. Say you have other chars like ^ or + in your react-native package dependency delcaration in package.json?

Maybe your parseFile function already takes care of that? Haven't gotten the chance to read through all the source code.

Otherwise, 👍

Nope it doesn't take care of that, good catch! I'm going to use an npm package compare-versions to check the versions so I don't have to write the parsing logic myself :) thanks again for reviewing!
