`--ignored-dirs` argument ignores the project itself

[orhun]

I'm not sure if this is the expected behavior but I came across this issue while I was working on #92

To reproduce:

$ cargo new repro
$ cargo build
# target directory is created
$ kondo
Projects cleaned: 0, Bytes deleted: 0.0B
# nothing is cleaned

I think this is due to:

kondo/kondo/src/main.rs

Lines 57 to 61 in 51828a1

	fn prepare_directories(dirs: Vec<PathBuf>) -> Result<Vec<PathBuf>, Box<dyn Error>> {
	let cd = current_dir()?;
	if dirs.is_empty() {
	return Ok(vec![cd]);
	}

might be regression in #90

Oh yep, I see what's happening, nice catch.

Should be fixed in a48eb09. Please let me know if there was still any issues :)

Works fine now, thank you for the fix!
