Smart Contracts: when contract does not output a tx (even if it crash), a transaction should still be created

### Is your feature request related to a problem?

Miners should get fees even if a contract does nothing or crash. This is an anti-spam solution.

### Describe the solution you'd like

ps: we probably need to copy the fields from previous transaction
ps: we probably need to change the `get_calls()` function as well

### Additional context

Epic: #608

Start with epic #608 and trace the transaction path relevant to smart contracts that produce no output or crash. Read the existing get_calls() behavior and determine which fields must be copied from the previous transaction. Done means a transaction is still created in these cases so miners can receive fees.
