Next version of React Native

[jamonholmgren]

This issue replaces infinitered/ignite#957 for tracking React Native version bump from 0.42+.

React Native 0.43 and 0.44 use React 16.0.0-alpha which isn't very friendly with React Native. @skellock recommends we wait for 0.45 before updating ignite-ir-next.

I have 0.44 up & running on my active project here. I think as long as we're not using enzyme and react-native-router-flux and are ok with a few warnings showing up (like reactotron-react-native - i know, i know), then 0.44.x is fine to upgrade.

[skellock]

I'll add react-native-maps into that mix too. they just refactored their codebase, and it might no longer be compatible. We'll have to revisit that as well.

Make the pain stop @jamonholmgren .

Now that we're off react-native-router-flux, we good to upgrade.

There is a minor issue with warnings appearing (Facebook's issue), but running yarn a final time or npm dedupe makes the warnings go away (they are with the library bser).

I say, let's hold off for a week, then go to 0.45.0.

(BTW: If anyone wants to use 0.44.2, you can run ignite new Latest --react-native-version 0.44.2 in the meantime).

We're now using 0.42.3 as of 2.0.0-rc.6.
