Configure Jest for mobile testing

[sliptype]

Description

• Configure Jest to run successfully for the mobile app
• Use babel to compile typescript instead of ts-jest which wasn't working due to Flow files with .js extensions in the react-native codebase

  The drawback to this is that our tests won't be typechecked when run

• Add babel plugin to transform react-use imports so that browser env specific hooks aren't imported

Coming next:

• Test for the NavigationContainer linking config

Dragons

Added process.env checks to determine if running via Jest. Will confirm that doesn't break anything in non-test envs
