Verify that drawer in tabs works with RNGH

This pattern is kind of silly but sure let's I guess make sure it works. #4714

Indeed.

I can verify that it works, although you might be looking for a PR with a test.

"react": "16.5.1",
"react-native": "0.57.2",
"react-navigation": "^3.0.0-rc.5",
"react-native-gesture-handler": "^1.0.9",

The pattern doesn't have to be that silly: you can use the drawer for other purposes, like filtering/sorting a main view without actually navigating, using a custom drawer component. Which might not be the intended or most obvious use-case of react-navigation, but hey. :)

thanks @evert-smit! yeah at some point we should add automated ui tests, i'll maybe look into that after releasing 3.0 proper soon
