Differences of resolving Sync trait requirements

I tried compiling module against [this crate](https://github.com/picodata/tarantool-module) and while it compiles just fine without Bazel,
seems like rules_rust handle something differently which results into compiler complains. The rules_rust version is latest 0.10.0

```
error[E0277]: `Rc` cannot be sent between threads safely

The repository is defined manually like this

```
crates_repository(
name = "no_cargo",
lockfile = "//third_party:Cargo.Bazel.lock",
cargo_lockfile = "//:Cargo.lock",
packages = {
...
"tarantool": crate.spec(
features = ["schema"],
version = "0.6",
),
...
},
splicing_config = splicing_config(
resolver_version = "2",
),
render_config = render_config(
default_package_name = ""
),
)
```
