Test/AI: check new misbehaviour_repr fields

Context

Update the tests to check the new Misbehaviour_repr.t fields introduced in !11575 (merged).

Manually testing the MR

dune exec src/proto_alpha/lib_protocol/test/integration/main.exe -- -f test_adaptive_issuance_roundtrip.ml

dune exec src/proto_alpha/lib_protocol/test/integration/consensus/main.exe -- -f test_double_attestation.ml

You can also observe that the roundtrip tests fail after Alpha/test_adaptive_issuance_roundtrip: update denunciation compare and pp but before Alpha/test_adaptive_issuance_roundtrip: correctly fill out new fields.
