refactor(substreams): add rust-toolchain to the templates and modules. (#155)

* refactor(substreams): add `rust-toolchain` to the templates and modules.

This freezes the wasm output for each module, allowing us to have full control over each packages and when we break the modules hashes.

* fix(testing): allow no `initialized_accounts` in tests
