Update Android Gradle Plugin to 4.0.2

[oguzkocer]

This PR updates Android Gradle Plugin to 4.0.2 which matches the current FluxC version, so it can be used for composite builds. We plan to update it to the latest version as soon as we can, but that work will be more involved, so for now we are just making a minor version bump to match our versions.

To test:

• As long as it builds and runs, we should be fine.

Thank you for fixing this so quickly @oguzkocer! I really appreciate this 🙇

I tested this and the Android app builds and runs as expected with composite build with WordPress-FluxC-Android 🎉

Since I noticed the same issue with gutenberg-mobile/gutenberg I also created wordpress-mobile/gutenberg-mobile#3542 and WordPress/gutenberg#32144 respectively.

I tried updating WordPress-Utils-Android too but run into another issue (probably related to my java version). I also wasn't sure if this project needs to be updated too (haven't really used to till now).

A problem occurred configuring project ':WordPress-Utils-Android:WordPressUtils'.
> Could not resolve all artifacts for configuration ':WordPress-Utils-Android:WordPressUtils:classpath'.

@antonis Unfortunately I didn't have time to work on this today. I think on gutenberg projects, there are a few more instances that needs to be updated. I'll also take care of the utils one, it looks like there is an issue with our Gradle plugin which is supposed to be updated to a new version.

Hopefully this is not blocking you, but if it's, let me know and I'll try to prioritize it.
