Fix issues with publishing (#462)

* Include `.scale` files

At the moment it's only `src/cmd/extrinsics/runtime_api/contracts_runtime.scale`.

* Fix `cargo publish`

* Add CI stage for `cargo package`

* Remove unused import

* Revert "Add CI stage for `cargo package`"

This reverts commit f1f5cb2.
