Dependency cleaning round (#1741)

### Description

We removed the warning message shown during the project build.

```
warning: the following packages contain code that will be rejected by a future version of Rust: traitobject v0.1.0
note: to see what the problems were, use the option `--future-incompat-report`, or run `cargo report future-incompatibilities --id 2`
```
The message is caused by an unused dependency introduced during #1615
