Allow for easier relocation of full sourcesets.

You can now call
    android.sourceSets.test.resetToRoot("blah/test")

and it will move all of src/test/* to blah/test/*

It makes it easier to migrate older project by relocating
non src/main outside of src/

Updated the 'migrated' samples to reflect this + other
misc fixes.
