Unbreak Crubit tests with the latest Rust compiler by allowing dead code in tests
The new version of the Rust compiler has started to identify dead code in our
tests, for example:
```rust
error: struct `SomeStruct` is never constructed
--> <crubit_unittests.rs>:2:28
|
2 | pub struct SomeStruct(f32);
| ^^^^^^^^^^
|
= note: `-D dead-code` implied by `-D warnings`
= help: to override `-D warnings` add `#[allow(dead_code)]`
error: aborting due to 1 previous error
```
