Subject: [PATCH] KTIJ-585 [Gradle Runner]: main() cannot be launched from AS
 4.1

Android gradle-project model differs from what we have for pure Java
and MPP. It's the reason why application classpath cannot be collected
correctly.
Until universal solution is provided delegation to gradle is put under
the registry flag. If disable platform runner is used as before.
