Sergey Pepyakin 2414ffdac0 Fix sandbox::Memory lifecycle + sandox get memory function for no_std env (#845)
* Fix `sandbox::Memory` lifecycle for no_std env

* Retain memories in env_def builder and instance

* Add scoped memory creation to test RC semantics

* Add deploying_wasm_contract_should_work test.

* Fix sandboxed memory set function.
