Fix failing cardano-constitution tests

Executing `cabal test cardano-constitution-test --test-option "-p /Golden/"` causes ten tests to fail: see the attached output. It's not immediately clear what the problem is, but many of the failures are budget tests. We should work out what's wrong and fix it. It may just be a matter of using `--accept`, but we should understand what's caused the problem first.

----------
Also, there's a sporadic error that can be reproduced by
```
cabal test cardano-constitution --test-option "--quickcheck-replay=(SMGen 11481876245814893229 13091201211930954589,3)" --test-option "-p /hsValidatorsAgreeAll/"
```
This seems to be a separate issue.
