Fixed length of root field in tx receipt response

[Vovchyk]

This sets the length of the root field that's being returned by eth_getTransactionReceipt JSON-RPC call to 32 bytes.

Description

Right now rskj returns 0x00,0x01 instead of 0x0...0 and 0x0...1 (32 bytes) for the root field. This makes some js libraries incompatible with rskj.

Motivation and Context

This change is required for the rskj node to be compatible with client libraries at the JSON-RPC level.

How Has This Been Tested?

JSON-RPC response of eth_getTransactionReceipt has been checked.
