Improve returned error when withdrawing with an unregistered script

[mpizenberg]

I tried to withdraw 0 with an unregistered script, and eternl send me back the following error message:

[{"code":3141,"message":"The transaction contains incomplete or invalid rewards withdrawals. When present, rewards withdrawals must consume rewards in full, there cannot be any leftover. The field 'data.incompleteWithdrawals' contains a map of withdrawals and their current rewards balance.","data":{"incompleteWithdrawals":{"stake_test17z2vfr5qxac9fpkdh8vhy3j2r9xfyzyr880hfx3ayvqd0qc7u40jp":{"ada":{"lovelace":0}}}}}]

It might be better if the error message could say instead that the script is not registered.

Here was the Tx I tried to submit:
