E2E Tests with detox

[DanielMSchmidt]

Currently we can only test the programmatic behavior and that only to a certain extend, but at least we good pretty cool e2e tests. Special thanks to @dbanck for helping me with this!

TODOs:

• integrate a CI to run the tests
• test opening and closing by swipe guestures (waiting on [feature] Configurable Swipe guestures wix/Detox#128)
• test if drawer opens left or right (waiting on Get coordinate of element wix/Detox#129)

Nice to have:

• test opening and closing animation (waiting on Test animation progress wix/Detox#130)
• test open / closed state of keyboard (maybe through visible / invisible box at the end of the view
• test orientation change
• test interaction handle for heavy load on animations

Although there are some issues with detox, I have to say it is a super awesome tool, thanks at @rotemmiz and the devs at @wix for making it happen 🎉 !
