fix(nano): avoid exception when generating json

[jansegre]

Motivation

Calling a method from a voided contract could make generating the JSON of a transaction fail.

Acceptance Criteria

• Add accept_failed_execution: bool to nano_header.get_blueprint_id so JSON can be generated
• Add test that reproduces a situation that would trigger the error

Checklist

• If you are requesting a merge into master, confirm this code is production-ready and can be included in future releases as soon as it gets merged
