redundant-clone: doesn't see redundant clone

[Paladynee]

Summary

redundant-clone doesn't work through match arms or something

Reproducer

Code:

pub fn try_from_bytes(bytes: &[u8]) -> Option<Vec<Vec<u8>>> {
    let mut pipeline = Vec::new();
    let mut index = 0;
    while index < bytes.len() {
        let c = bytes[index];
        match c {
            0 => {
                let algo = vec![];
                pipeline.push(algo.clone());
            }
            1 => {
                let algo = vec![];
                pipeline.push(algo.clone());
                return Some(pipeline);
            }
            _ => {}
        }
        index += 1;
    }

    None
}

this is as small as i could get it, the clone in the 0 => { match arm isn't caught, while the one in the 1 => { arm does

Current output:
one of the clones aren't detected

Desired output:
both clones are detected
