Is your feature request related to a problem? Please describe.
Neo Express will only return the transaction results if you send the --results flag. However, these transactions aren't saved. If we use the --account parameter, the transaction is saved but the response is the transaction hash and not the results.

Describe the solution you'd like
Add a flag or equivalent to the contract run feature (using an account parameter) to return the transaction results instead of the transaction hash.

Additional context
The output can be too verbose if we include all the transaction fields. It could print the existing 'results' fields plus the transaction hash:

VM State: FAULT Gas Consumed: 1111470 Exception: Index was outside the bounds of the array. Transaction: <hash>
