contracts/call errors out when transaction.to is set to null

[quiet-node]

Description

Currently, when a request with transaction.to=null is sent to contracts/call endpoint, mirror-node throws an error with message to field must not be empty. transaction.to is set to null in the case of deploying a contract, and contracts/call should accept a transaction object with nullable to field.

Steps to reproduce

1. Run below cURL request

curl -X 'POST' \
  'https://testnet.mirrornode.hedera.com/api/v1/contracts/call' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
  "block": "latest",
  "data": "0x6080604052...",
  "estimate": false,
  "from": "0x9de0881b3110aA8cAD1dF3182B1eB6F14d1608a2",
  "gas": 15000000,
  "gasPrice": 100000000,
  "to": null,
  "value": 0
}'

2. Observe the output to see the error message like below

{"_status":{"messages":[{"message":"to field must not be empty","detail":"","data":""}]}}
