fix circuit-bug and add more tests (and update Nargo.toml)

[FilipHarald]

I found a bug when adding tests. It turns out to also be a bug in Noir. I'm working on it here: https://github.com/Kryha/scaffold-eth-2-noir/tree/test/more-circuit-tests

And also talking to them on their Discord.

Here is the issue : AztecProtocol/aztec-packages#1845

More likely it's going to be updated here: AztecProtocol/aztec-packages#1844

currently waiting for their issue to be resolved...
