Unable to compile to target wasm in v0.9.2 with cw-multi-test v0.19.0

I am using sylvia v0.9.2 which has a dependency on cw-multi-test v0.19.0.

When trying to build the contracts with a wasm as target (using rust-optimizer), the following error occurs:

error[E0432]: unresolved import `cosmwasm_std::testing`
 --> /usr/local/cargo/registry/src/index.crates.io-6f17d22bba15001f/cw-multi-test-0.19.0/src/addons/api/bech32.rs:2:19

As a result, I am unable to build the contracts. Perhaps we can only have cw-multi-test as dependency on dev / test.

Hi @whalelephant please upgrade to sylvia 0.9.3. cw-multi-test was unnecessarily enabled when cosmwasm_1_x features were enabled and is not anymore.
