AssetHolding is missing the creator

[winder]

Summary

The asset holding objects in algod include the creator. Indexer does not.

Scope/Requirements

There are a few options:

1. At the REST layer lookup the creator for each asset holding and attach it to the API response
2. Add it to the account_asset table so that there is no lookup.
3. Update the query so that postgres adds it to the results in the backend.

Urgency/Relative Priority

This would probably be a nice feature to add, but there is a simple workaround. If needed search for the asset by ID instead of the creator.

I think this is still an issue.

It seems like the creator was added to the asset holding, but now it has been removed again? Can someone confirm this? Did not find anything about that in the changelog.

I believe the creator was removed from the holding object in algod when we uncapped the asset/application limit.
