Should we add some info about the fallback method? At least a flag stating whether it's available.

Postponed thread.

FIX: I think there's a bug when searching for a contract created by another contract, because this method assumes the nc_id is a tx.

[glevco]

I'm changing this to a postponed thread. It's not critical because it only affects the search feature on the nc_creation explorer API.

Initially I thought it would be a simple fix on the resource itself, but that's not the case. The NC creation index only stores the tx's hash and timestamp, therefore it's not possible to use it to retrieve a tx via a contract id when that contract was created by another contract.

The fix is more involved and relates to other improvements in all explorer APIs. Those should be addressed in future PRs. A partial implementation (well, just a test) was started in fix/nano/nc_creation_by_another.
