Incorrect clippy::needless_return on async tests in latest nightly

[amircodota]

Summary

In the latest nightly, on tokio::test functions, the last assert is flagged with clippy::needless_return

Reproducer

I tried this code:

#[tokio::test]
async fn test1() {
    assert_eq!(4, 5);
}

And ran this

cargo +nightly clippy --all-targets --all-features 

I expected to see this happen:

I expected clippy to pass

Instead, this happened:

It write this error

 --> src/main.rs:7:21

Same issue with tokio::main.

use anyhow::Result;

#[tokio::main]
async fn main() -> Result<()> {
    Ok(())
}
