Add a method returning LedgerEntryType of ingest.Change

Both can be set but it doesn't matter because the type cannot be changed. We basically want to extract ledger entry type from the change. I guess this should be a method on ingest.Change.

This issue wasn't about LP type (still cool we have it now!) but Ledger Entry type. Reopening.

I think I am a little confused here. Is this different from just referencing change.Type?

Oh, you are right. Somehow I was thinking that change.Type is LedgerEntryChangeType. Closing.
