speeds up rewind by adding indexes

After adding indexes for 'hive_row_id' of registered tables
rewind is faster 100x than previously, but still much slower
than fully optimized algorithm.

Adding indexes slows down edit operations from 20% to 80%(for massive delete).
But still this are not siginificant absolute values.
