fix: eth_getTransactionByHash correct response parsing

[stoyanov-st]

Description

Running the Ethereum Execution Spec Tests against Solo environment uncovered some inconsistencies in the response of etc_getTransactionByHash.

1. gas field was assigned from gas_used instead of gas_limit -> fixed and adjusted the related tests.
2. value field was providing wrong response due to overflow of the numeric type -> cast to BigInt and adjusted related tests.

Testing Guide

1. npm run test - to run unit tests
2. npm run acceptancetest - for acceptance tests
   For manual testing
3. Submit transaction with gas limit set to 0xf4240 and value 0x36183a660c8eff1c00
4. Query eth_getTransactionByHash with the transaction hash
5. Expect the returned gas field to be the exact 1M and value to be 997869999990000000000 initially provided
