Updated git submodules

Project: genius master 4737e872a897f3f366c013f7a5d9a5b6617515f5

Clean up MDSALManager.removeGroup()

Removing a group only needs a DPN and group identifier; deprecate the
other forms, add a simple variant of removeGroup() and remove
duplicates.

This patch also moves the test package so that we avoid needing to
make methods public.
