fix(nano): state API regression after ctx.address refactor

[jansegre]

Motivation

When we refactored ctx.address into ctx.caller_id we also introduced specialized classes Address(bytes), VertexId(bytes), etc, and those broke a if type(value) is bytes check, either way that check was not the correct way to do it.

Acceptance Criteria

• Fix state API to return the value properly formatted (like its NCType specifies)
• Expand the existing test to have fields of types Address, VertexId and others

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
