Update transactions, receipts and logs queries (#173)

Browse Source 
* Update queries to fetch data from cids tables

* Fix eth_getTransactionByHash to return tx from canonical block

* Fetch transaction by hash in a single query

* Update queries to fetch data from IPLD blocks table

* Avoid NULL result from canonical block hash query

* Update GitHub workflow and script to run unit tests

* Avoid usage of LIMIT 1 in queries for GQL API

* Fetch IPLD data separately when retrieving latest account data or storage value

* Upgrade geth dependency

* Update GitHub workflow
