Add missing contracts api to acceptance tests

[ashumahajan]

Problem

We're missing acceptance test coverage for some contracts mirror node REST APIs.

Solution

Based on #4051 , add below apis coverage to acceptance tests

1. /api/v1/contracts - List all contracts
2. /api/v1/contracts/{id}/state - Contract state
3. /api/v1/contracts/{id}/results/{timestamp} - Contract results by timestamp
4. /api/v1/contracts/results - All contract results
5. /api/v1/contracts/results/{id}/opcodes - Contract opcodes
6. /api/v1/contracts/{id}/results/logs - Contract logs by contract
7. /api/v1/contracts/results/logs - All contract logs
