Adapt testnet debug/tracers tests so they use Solo instead except for the call ones

[freemanzMrojo]

Summary

https://github.com/vechain/thor/releases/tag/v2.1.4-rc.3 disables some of the debug/tracers methods (look for the GitHub issue ID in the codebase) so some of the testnet tests are disabled.

The purpose of this ticket is to adapt them so they point to solo instead, while remaining the call ones for testnet.

Basic Example

The error we are getting is as follows:
