Disable deleting classes.dex in Intellij Idea

In the AndroidDexBuilder class remove outFile.delete() statement and rebuild android-jps-plugin.jar.

The simplest way to do it replace delete string with exists in the AndroidDexBuild class in the idea-$VERSION/plugins/android/lib/jps/android-jps-plugin.jar archive.
