Build Error when using v3.3.0vending minter and factory contract packages

[kromsten]

Same problem as in #616 except for building a project with vending-minter as a dependency.

Happens during compilation of vending-factory and crashes due togetrandom crate

error: the wasm*-unknown-unknown targets are not supported by default, you may need to enable the "js" feature. For more information see: https://docs.rs/getrandom/#webassembly-support
