Remove pointless method duplication
Merge branch 'hadoop-reindex' of github.com:thinkaurelius/titan into hadoop-reindex
Copy index test changes from TitanGraphTest

This commit copies the index test changes made in
d4fd2a292b9e501b375569f135c14535ee1ffd9a to the test of Faunus-based
reindexing.  Still not the cleanest way to organize these classes but
the test passes.
