Detox: Android app crashes on launch with latest Detox & React Native

[brunobar79]

Describe the bug

To Reproduce

• [x] I have tested this issue on the latest Detox release and it still reproduces

Steps to reproduce:

1. Run detox build -c android.emu.debug
2. Run detox test -c android.emu.debug
3. App crashes after launch

BTW. I can manually launch the app after that and it works fine.

This is the crash log from adb logcat

@brunobar79 We do not yet officially support RN .62, both because it's in RC but also b/c we're waiting for feedback regarding internal Detox integ. work currently in progress (see #1886).

@brunobar79 @d4vidi Found this one too.. exactly the same... still happen in newest RC..

Environment:

• Detox: v16.0.1
• React Native: v0.62.rc.5

RN .62 is not yet officially supported by Detox (Android), although we _did_ expect it to work immediately since it is now in part integrated into RN itself. Nevertheless, now that .62 is out of beta we'll smooth things out asap.
