Not handling contract creation transactions #25
Description
Issue:
When passing contract creation transactions, Tx explain returns 'error: 1 validation error for Transaction to_address none is not an allowed value (type=type_error.none.not_allowed)'.
Since contract creation transactions don't have to_address, Tx explain can't process them. Backend needs to be adjusted for this.
