Adding "reuse": true to configurations doesn't do anything

[kdenz]

• Detox: 6.0.4
• Node: 8.5
• Device: iOS 11.2
• Xcode: 9.2
• macOS: 10.13.1

I'm using Jest

According to @dariocavero in #143 (comment) , it's possible to add "reuse" under detox's config like this:

My scripts in package.json

My init.js under e2e folder

My config.json under e2e folder

But it's not working, in the end I'll need to use detox test -r to make reuse work.

The reason I would prefer not using detox test is because it seems like detox test doesn't support flexible optional testing, such as if I just want to test the Welcome screen and not others. I can do this with jest WelcomeScreen. And also the unit and e2e tests can easily be chained together.

This can be a welcome PR
https://github.com/wix/detox/blob/master/detox/src/devices/Device.js#L26

You'll need to also check if the app is installed on the device, and if not, throw an error
