🐛 - Fix Android crash: Unable to instantiate fragment (#390)

Crashlytics started to report the following crash on Android devices: ``` Unable to instantiate fragment com.swmansion.rnscreens.ScreenStackFragment: calling Fragment constructor caused an exception ``` A thrown error has suggested this fix: ``` Screen fragments should never be restored. Follow instructions from software-mansion/react-native-screens#17 (comment) to properly configure your main activity. ``` We had the `MainActivity.java` configured properly, but when migrating to Kotlin on the latest version (2.3.3), we forgot to add it to `MainActivity.kt`.
