Add dependencies to package.json

Summary:
I extracted all the dependencies (using jest-haste-map) and copied them from the package.json in react-native to RNP. There is some duplication here for now but we can later go back and remove the duplicated dependencies from react-native that aren't needed there.

I also removed a mock file that hasn't been in use for a long time.
