This case expression and a ledger COMPLETE pragma currently disagree, only on this case.

I currently include a commit in this PR that assumes the COMPLETE pragma is right and the case expression was wrong.

But I'm not sure what exactly the body of this UpdateDRepTxCert should be. For example, should it use conwayToObject instead of the drepCredJson I added?
