Investigate react-native-gradle-plugin related error

[hvge]

After changes introduced in #42 there's weird error reported when example application's project is opened and build from Android Studio:

Executing tasks: [:react-native-gradle-plugin:compileJava, :react-native-gradle-plugin:testClasses] in project /Users/xxxxx/react-native-malwarelytics/example/node_modules/react-native-gradle-plugin


FAILURE: Build failed with an exception.

* What went wrong:
Project 'react-native-gradle-plugin' not found in root project 'react-native-gradle-plugin'.

In fact, it's reported only in Android Studio and when you try to build the project (CMD+F9). When the build is initiated by yarn android or by ./gradlew assembleDebug or if you try to run app from the studio, then everything's OK.
