Fixes #6121.

This bug happened because we were only adding labels for unindexed params. We now need to restore the order of the indexed and unindexed params as alloy returns them separately, to be able to assign the labels properly.

inputs.push(decoded.indexed[indexed].clone());

I feel like this should be supported by DecodedEvent perhaps

Yep definitely, we should be able to do this through a method rather than manually

Yeah? Seems unrelated, from an external integration test that probably changed
