This change simplifies the logic for indexing transactions and enhances the UX when transaction is not found by returning more information to users. Transaction indexing is now considered as a part of the initial sync, and `eth.syncing` will thus be `true` if transaction indexing is not yet finished. API consumers can use the syncing status to determine if the node is ready to serve users.
