AGP 4.0.0 brings in a change which wipes out the output files whenever a task gets rerun
See https://android.googlesource.com/platform/tools/base/+/studio-master-dev/build-system/gradle-core/src/main/java/com/android/build/gradle/internal/tasks/NonIncrementalTask.kt
The manifest merging task tries to update the manifest in place, by setting input == output, resulting in the input file being explicitly deleted just before the task gets run
Fix by making input != output, by setting input to some arbitrary copy location in the fat-R directory
