Duplicated tests when combined with `test_log`

It's unclear to me if this is really a bug or just the expected outcome of Rust's weird test case registration system.

```
❯❯ cat Cargo.toml
[package]
name = "t"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
test-case = "3.3.1"
test-log = "0.2.16"

[[bin]]
name = "t"
path = "main.rs"

❯❯ cat main.rs
fn main() {
println!("Hello, world!");
}

mod tests {
use test_case::test_case;
use test_log;

#[test_case(1; "pollo mundo")]
#[test_log::test]
fn test_once(_arg: u8) {
assert!(true);
}
}

❯❯ cargo test
Finished test [unoptimized + debuginfo] target(s) in 0.02s
Running unittests main.rs (target/debug/deps/t-fe670cbfe3e221f9)

running 2 tests
test tests::test_once::pollo_mundo ... ok
test tests::test_once::pollo_mundo ... ok

test result: ok. 2 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.00s
```

Any idea if there's a workaround for that? In this case it's quite easy to drop `test_log` but I guess there might be many similar cases where the test wrapper macro is more valuable.
