I think we don't need INSPECTOUTPUTNONCE when we already checked that value and asset are explicit

The code above that checks that both value and asset of output 0 are non-confidential.

I used the 'nonce is empty' check in my early covenant code as a belts-and-suspenders check, but now I'm really in doubt if it is useful at all, when we already checked that asset and/or value is non-confidential. As I understand, the nonce will be non-empty only if they are confidential.
