`test-env-log` used with `test-case` creates test duplicates

> When I use the latest `test-case` and `test-log` (new name of `test-env-log`) together, I get duplicate copies of each test generated.
I also tried it with what I think were the versions from when this issue was created and have the same problem.

[Full example in this gist](https://gist.github.com/newsch/6ec5dfc835c355f7943f55d9c01d88f6#file-main-rs=)

```rust
#[cfg(test)]
mod tests {
use test_case::test_case;

#[test_case(0, 0 ; "the same")]
#[test_case(0, 1 ; "different")]
#[test_log::test]
// #[test_env_log::test]
fn equality(a: usize, b: usize) {
log::info!("a: {}", a);
log::info!("b: {}", b);
assert_eq!(a, b)
}
}
```

Output

```
