> The new secondary index API does not notify indexes of single-row or slice deletions
unless specific columns are deleted.  I believe the problem is that in {{SecondaryIndexManager.newUpdateTransaction()}},
we skip indexes unless {{index.indexes(update.columns())}}.  When no columns are specified
in the the deletion, {{update.columns()}} is empty, which causes all indexes to be skipped.
> I think the correct fix is to do something like this in the {{ModificationStatement}}
constructor:
> {code}
> if (type == StatementType.DELETE && modifiedColumns.isEmpty())
>     modifiedColumns = cfm.partitionColumns();
> {code}
> However, I'm not sure if that may have unintended side-effects.  What do you think, [~slebresne]?
