closes #341

I don't like checking the errors in test by comparing strings - I would really prefer to switch to proper error types (we have thiserror anyway), and if needed converting them to string at the end. If for simplicity we want to unify error types, then we could just go with handling them with anyhow so if needed, error types can be retrieved by downcasting.

Looks good.

I would remove the events echo in reply and add some trim spaces to the length checks. Then good to merge

I would actually not add these to the reply call. These should be appended by the runtime when there is a SubMsg executed without the reply blob doing anything

Note in the real wasmd implementation, we trim off whitespace from the ends before checking empty, so " " is also invalid.

The relevant Go code changes are are https://github.com/CosmWasm/wasmd/pull/562/files maybe you can use them as reference

Same thing, I think we trim whitespace before checking length
