duplicated extension status: Add the same test as for go-verkle

No description provided.

the test fails, because it tests for an agreement with the output of go-verkle, thus demonstrating the problem

Thanks for the PR, currently checking if this deduplication can be introduced after we've produced the proof of absence stems instead of introducing an edge case when collecting the proof of absence stems
