Also, fixes setting mock_env hash.

However, I am testing it out in my example contract, and setting admin from rust does not appear to be working. Is there maybe some reason the admin param wouldn't be read automatically on the GO side? ... It very well could be a mistake on my side, I'm still testing it out. I'm using a local secret v1.11.0 instance

here's where I'm setting it for reference:

Thanks! I'm afraid that's a bug that we'll need to fix in a future upgrade. 😢

Damn, I kinda need this at least on testnet :/. I looked in the SecretNetwork repo and found the rust types there were also missing the admin param, add them in a pr. Not sure if other additional work is needed as I can't build it on my mac. But that's probably the most I can help.
